From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows 98)

When i try to start build m14 on windows 98 the program crashes and i get the 
following error: 
MOZILLA caused an invalid page fault in
module UCONV.DLL at 0177:607f4905.

Reproducible: Always
Steps to Reproduce:
1.Just simply start the program on windows 98
2.
3.

Actual Results:  It crashes

Expected Results:  The browser should have started
It could be related to bug #31847 "browser crashes on startup"
Summary: I can not start the browser. → I can not start the browser.
Can you try a new build?  M14 is over 2 weeks old now, and in all likelihood
whatever caused this has been fixed.
goldalex@optonline.net please downlad and test with a newer build.  Also, do you
have a personal firewall set up, something like WinGate or Zone Alarm?  if so
this is probably a duplicate of bug 28403 which has been fixed.  Please report
back or this bug will be marked WORKSFORME.  Thanks

reporter's comments from email:



  I tried to download the latest nightly build as of 3-24-00 and the browser 
still does not start. The splash screen
  starts up and then nothing, and then the splash screen dissapears. I am using 
wingate over a phonline network on
  Windows 98.
Reporter, I've suggested that they reopen bug 28403 until Mozilla works with 
WinGate.  The problem is definitely related to the firewall. All of these bugs 
(there are quite a few duplicates of 28403, both from Zone Alarm and WinGate) 
crash in teh same place.  Mozilla works with Zone Alarm now so that bug was 
resolved fixed.  If they do not reopen that bug then this will become the new 
bug for tracking the WinGate problem.  Take a look at the workaround steps in 
bug 28403 to see if you can get WInGate to play nicer with Mozilla.  I'm going 
to confirm this and assign it to the folks that fixed 28403.  If they reopen 
28403 we can mark this a duplicate of it.

If I disable wingate and then start the browser the browser  starts but i
can not get online due to wingate being disabled if wingate is active the
browser does not start I am using build 2000032308 on windows 98
Target Milestone: M16 → M17
The same bug is now occuring in teh beta release of netscape 6 it crashes on 
start up. I get the following message:  NETSCP6 caused an invalid page fault in
module XPCOM.DLL at 0177:60c28350.

Once again if I disable wingate the browser starts. But of course I cant get 
access to the net.
Summary: I can not start the browser. → Browser does not start if Wingate is enabled
I debugged this problem and this is what I found:

I traced the problem to the following code in prsocket.c:

    PR_InitializeNetAddr(PR_IpAddrLoopback, port, &selfAddr);

    /*
     * Only a thread is used to do the connect and accept.
     * I am relying on the fact that PR_Connect returns
     * successfully as soon as the connect request is put
     * into the listen queue (but before PR_Accept is called).
     * This is the behavior of the BSD socket code.  If
     * connect does not return until accept is called, we
     * will need to create another thread to call connect.
     */
    if (PR_Connect(f[0], &selfAddr, PR_INTERVAL_NO_TIMEOUT)
            == PR_FAILURE) {
        goto failed;
    }

The PR_Connect fails in the WinGate case.

I am using mozilla code from last Wednesday night.

Netscape PR1 fails as well.

The reason there is an XPCOM trap on Netscape release is because of an assert in 
XPCOM shutdown.

The actual bug appears to be the PR_Connect failing

This component is marked Internationalization, is that really correct?

copying dp@netscape.com just in case this is his and not i18n.
Cata, this look more NSPR to me; NSPR doesn't work with Wingate ? wtc ? 
srinivas ?
The only reason this bug is assigned to
the Internationalization Component is that
the crash occurs in UCONV.DLL.

mkaply@us.ibm.com reported that this may
be caused by the failure of the PR_Connect
call in PR_NewPollableEvent:PR_NewTCPSocketPair.
I've opened NSPR bug #35408 to investigate
that.
Yes, this bug is assigned to me only because the crash takes place in uconv.dll 
Otherwise, this has nothing to do with i18n. Unless I am not handling an error 
condition gracefully. mkaply, can you give us a stack trace?

Anyways, who I should reassign this bug to? wtc? Or mark it as duplicate of 
#35408?
Let's assign this bug to me for now.
Assignee: cata → wtc
Status: ASSIGNED → NEW
Depends on: 35408
*** Bug 28403 has been marked as a duplicate of this bug. ***
I put code to prevent it from crashing and fall back on using poll with 
small timeout when PR_NewPollableEvent fails.
Larry checked in the fix for bug #35408.  With
that fix PR_NewPollableEvent will succeed if
WinGate is enabled.  If PR_NewPollableEvent fails
for some other reason, Ruslan's checkin to fall
back on using poll with small timeout will prevent
the browser from crashing.

Marked the bug fixed.

Even witht the fix accsess can still not be gained to the net but the browser 
does start.
If you can't gain access to the net, please
open another bug report so that we can track
it.

This bug is concerned with the crash in
UCONV.DLL at browser startup.
