Bug 104985 – mozilla-firefox crashes with BadShmSeg

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Martin von Gagern 2005-09-06 02:26:55 UTC]

Most of the time when I visit the map24 page, my firefox (compiled from source)
crashes, and if I started it in a terminal window, I get an error message as
described below. Sometimes everything works fine...

Reproducible: Sometimes
Steps to Reproduce:
1. Start firefox
2. visit http://www.map24.de/
3. search for some place or route

Actual Results:  
New
SetWindow
SetWindow
Destroy
The program 'Gecko' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadShmSeg (invalid shared segment parameter)'.
  (Details: serial 785 error_code 178 request_code 147 minor_code 2)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
firefox-bin exited with non-zero status (1)

Another time, the serial was 86 instead of 785.

Expected Results:  
Map displayed using java.

As this looks somewhat like the bug described here:
https://bugzilla.mozilla.org/show_bug.cgi?id=189573
and this is a flash issue, some additional info about flash.
I'm using gplflash, with the following flags:

net-www/gplflash-0.4.13  +alsa -debug +oss

[Comment 2 Martin von Gagern 2005-09-06 03:05:59 UTC]

Same problem with www-client/mozilla-firefox-bin-1.0.6-r2; it was serial 
342 this time.

[Comment 3 Martin von Gagern 2005-09-06 04:59:55 UTC]

I recompiled mozilla-firefox and gplflash with USE=debug. I started firefox with
--debug and --sync and tried to set a breakpoint on gdk_x_error. I got the same
error again, but the debugger did not stop at the breakpoint. So I still have no
stack trace.

[Comment 4 Jory A. Pratt 2005-12-11 15:44:20 UTC]

Most gplflash will not work with current  gecko based browsers. I would suggest
you remove the plugin and use netscape-flash or wait for gplflash2 to get to a
useable state.
