User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.5b) Gecko/20030827
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.5b) Gecko/20030827

browser crash when downloading certain files. These appear to be files of type
application/postscript. Mozilla 1.4 put up a dialog box asking "what do you want
me to do with this file?" 1.5b simply crashes. No console messages.

Reproducible: Always

Steps to Reproduce:
1. make sure no helper app for application/postscript
2. attemp to download http://people.cs.uchicago.edu/~fortnow/beatcs/column80.ps
(or visit http://people.cs.uchicago.edu/~fortnow/beatcs/ and click on one of the
links, excepting those that explicitly indicate "PDF")
3. 

Actual Results:  
browser will crash

Expected Results:  
bring up "what do you want me to do with this file" dialog box

Works properly on 1.4

Any chance of a stack trace (eg from MacsBug)?

Comment 2

[Loren Rosen]

Wouldn't gdb make more sense than macsbug? But I've no idea how to run gdb on
MacOSX apps.

Alternatively, perhaps I'd actually get stack traces on the console if Talkback
wasn't allegedly enabled. Not that I've ever actually seen Talkback actually
come up after an OSX browser crash.

Loren, what version of Mac OS are you using? There are several reports by Mac OS
10.1.x users crashing (with no talkback and crash report) when trying to
download. Downloading works fine if "Save link target as..." from the contextual
menu is used. 
This could be a dupe of bug 213639. Other reports (probably dupes of bug 213639)
are bug 216497 and bug 217549.

Loren, do you see any message in the console when you crash?

[Boris Zbarsky [:bzbarsky]]

Loren, gdb would need an unstripped binary to do anything useful; it's really
only an option when compiling Mozilla yourself.

Comment 5

[Loren Rosen]

Using 10.1.5. No mozilla crash log, but in the main console I just notices there
are messages like this:

*** malloc[394]: Deallocation of a pointer not malloced: 0x1cee0; This could be
a double free(), or free() called with the middle of an allocated block; Try
setting environment variable MallocHelp to see tools to help debug

/Applications/Mozilla.app/Contents/MacOS/mozilla-bin: can't map file:
/Library/Internet Plug-Ins/MRJPluginCarbon.plugin ((os/kern) invalid argument)

What I'm seeing is the same or at very least a closely related bug to the others
you mention. For me, least, files will successfully download if either they have
a known helper application, or if the "save link target as..." contextual menu
is used.

should be fixed by bug 213639 checkin.
