Bug 50579 – gaim crashed while trying to connect to MSN

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Ricardo Correia 2004-05-09 14:53:44 UTC]

When I try to connect to MSN gaim crashes with a segfault after the "Password sent" message.
(I'm compiling with "-cjk +crypt -debug -nas -nls +perl +spell")

Then I compiled with USE="debug" and captured a gdb stack trace:

(gdb) run

Detaching after fork from child process 3120.

I searched the forums and I only found a reference to a bug with aspell 0.50.3. I tried with aspell-0.50.5 and with USE="-spell" but it crashes anyway...

Reproducible: Always
Steps to Reproduce:
1. Start gaim
2. Sign on
3. *poof*
Actual Results:  
Segfault 

Expected Results:  
Not segfault 

I'm using glibc with NPTL, vanilla kernel 2.6.5, gtk 2.4, xfree 4.3.0, updated 
gentoo..

One vital bit of information is which version and revision of gaim you are using.

[Comment 2 Ricardo Correia 2004-05-09 15:54:42 UTC]

I'm using gaim-0.77 (the latest stable version)

[Comment 3 Ricardo Correia 2004-05-09 20:17:07 UTC]

latest unstable (gaim-0.77-r2) also craps out at the same place..

[Comment 4 Don Seiler (RETIRED) 2004-05-10 09:10:40 UTC]

I can't duplicate, but a problem in strncpy() tells me that a buffer is being improperly used in upstream code.  Please re-file this bug in gaim's bug tracker on sourceforge.net.

Be sure to include gaim version and your backtrace.
