80881 - Save Image crash

Status: VERIFIED WORKSFORME

Description

[Marc Loiselle]

Steps to reproduce.

Visit http://en.carpoint.msn.ca/vip/Overview/Porsche/911/New.asp
Right click the Porsche image.
Select "Save Image ( )..."
Change the file name.
Click Save button.
Crash.  Download dialog does not appear and file is not created.

No crash if the filename is not changed.

Buildid 2001051421

BTW how can I generate a backtrace when there is no core.  ./mozilla -g then run
just displays "ptrace: no such process".

hmmm, strabnge behaviour on this one.
I am debugging with "ddd", not much more then a GUI for gdb. between clicking at
"save picture ()" and the appearance of the "where to save" window, i get the
following message:
"the mouse pointer appears to be frozes. continuing execution automaticly, which
reappears after clicking on "save".
my debugger also tells me the following: 
Document http://en.carpoint.msn.ca/vip/Overview/Porsche/911/New.asp loaded
successfully
warning: find_solib: Can't read pathname for load map: Eingabe-/Ausgabefehler

Cannot access memory at address 0x21.
(gdb) cont
Continuing.

I did not type the "cont" myself.
I see no crash and the picture is saved and does work.
Funny is the filename of this file: merismus\\Gallery\\c438763a.jpg
the folder structure  got saved within the filename. this seems to be a problem
of the webpage, since NS4.x does it similar (except it replaces the \\ with _). 

ok, i am not sure, how mozilla can survive the "Cannot access memory at
address0x21", but here Mozilla does NOT crash, also not without debugger. So I
would give it a WorksForMe.
I am using 2001051508 for Linux on a Suse6.4 system.

This depends on the GDB and the libs you have. at work I use the ancient
Suse6.4, where debugging works (gdb4.x) while at home with a quite recent
Suse7.1 I see the same message. 
There is bug 57051 about this (blocker, Moz 0.9.1), which you should read.

[Jens-Uwe]

Eingabe-/Ausgabefehler = I/O-error.

Comment 3

[Marc Loiselle]

Jens-Uwe: did you try changing the filename before clicking Save.  That is what 
causes the crash for me.  

Interesting that the suggested filename on Windows is c438763a.jpg while it is 
merismus\Gallery\c438763a.jpg on Linux.

ok, you got me. just another crasher in  NSGetModule. I tried to call the file
c438763a.jpg and can reproduce the crash reliable with 2001051508 for linux.


below the stack trace:

I'd bet dollars to donuts this has nothing to do with any xpapps code.  My tough
luck you happened upon this whild saving the file, I guess.

Comment 7

[Marc Loiselle]

wfm with cvs build from 20010520.

Comment 8

[benc]

mass move, v2.
qa to me.

Comment 9

[Marc Loiselle]

resolving to worksforme

Comment 10

[benc]

+crash, verifyme
VERIFIED:
WFM in Mozilla 0.9.2, Win98.
Since this is a crasher, I need to verify on all plats before I OK this....

Does necko to the file i/o when saving?

Comment 11

[Jens-Uwe]

verified wfm linux 2001071021.
benjamin: this bug was reported on linux, does it still have to be tested on all
plattforms?

Comment 12

[benc]

If verification is left to me, that is the standard of testing I will use.

If someone else thinks it is good, they can mark it verified.
