723900 - assert when typing into web development console

Status: RESOLVED DUPLICATE of bug 694594

(Core :: XUL, defect)

Description

[Jan Horak [:jhorak]]

Attachment: gdb bt aand DumpJSStack() output

I got assert when using firefox with xulrunner when trying to type into web development console (before debug build I got random crashes).

Assert is on:
growByImpl<false> (this=0x5f9c7d8, cx=0xb47400c0, wrapper=0xad7d61f0, flags=1, vp=0xb2efe188) at ../../dist/include/js/Vector.h:678

Attaching backtrace from JS and GDB.

Reproduction steps:
1. Open Web console (Tools/Web developer/Web console)
2. Start typing into ">" input line

I cannot reproduce this on released binaries, this issue is most likely related to firefox+libxul builds.

Can you please tell us more about the Firefox build you use?

Comment 2

It seems to be more related to optimalization that to ff+libxul. I can reproduce the same behaviour when compilation is done without libxul with -O2 (--enable-optimize). 

I'm using:
libstdc++-4.4.5-6.el6.i686
gcc-4.4.5-6.el6.i686

Check if you have the same crasher as in bug 694594. You have gcc 4.4.5 - maybe it has the same problem as gcc 4.4.3.

If that is the case: suggested workaround is to use a newer gcc or switch to clang (which is what I did).

Yeah, it looks like same problem. I encounter same problem as in bug #694594.
