[Description Vladimir 2010-01-20 14:18:57 UTC]

sci-mathematics/scilab-4.1.2-r2 doesn't want to start after installation.
Running it with "-debug" option gives the following output:

/usr/bin/scilab: line 355: 31256 Segmentation fault      $SCI/bin/zterm $zterm_arg -e gdb $SCI/bin/scilex $sci_args

Reproducible: Always

Steps to Reproduce:
1. emerge scilab
2. type "scilab" in the command line

Actual Results:  
Nothing happens (Scilab doesn't start).

Expected Results:  
Scilab should start.

same problem here

[Comment 3 Thomas Capricelli 2010-03-20 05:13:13 UTC]

same problem here with sci-mathematics/scilab-4.1.2-r2 on ~amd64:
% scilab -debug
/usr/bin/scilab: line 355: 28240 Segmentation fault (core dumped) $SCI/bin/zterm $zterm_arg -e gdb $SCI/bin/scilex $sci_args

[Comment 4 Urs Hunkeler 2010-03-26 09:07:59 UTC]

Same problem here. zterm (/usr/lib/scilab-4.1.2/bin/zterm) seems to be the problem. Running it in gdb gives:

Program received signal SIGSEGV, Segmentation fault.
0xb7b7a3b5 in gdk_window_set_geometry_hints () from /usr/lib/libgdk-x11-2.0.so.0

Re-emerging gtk+ did not help.

Currently I manage to use scilab with two workarounds:
- scilab -nw (to not use the scilab GUI)
- emerge scilab with -gtk (I get a warning that this is the last version to use the old graphics mode)

(In reply to comment #4)
I have this problem too (on x86) with the same version of scilab.

zterm[27417]: segfault at 50 ip b7162f54 sp bfb47220 error 4 in libgdk-x11-2.0.so.0.2000.1[b70fa000+94000]

I have to run scilab on Fedora machine until this bug is solved.

don't set geometry on unrealized widgets

This patch fixes the crash in zterm for me.
