Hi,

I could not produce any segfault, only some errors/sigabrt.

  * When using 'ulimit -u 300' and then executing chromium, I got the 
following error:
[29486:29486:1109/235602:ERROR:render_sandbox_host_linux.cc(348)] Could 
not get pid

Chromium opens, but when I try to create a new tab, it just closes with 
another error similar to the above.
This error message is quite clear about not being able to fork and the 
resource being temporarily unavailable.


  * When using 'ulimit -u 250' and then executing chromium, I got the 
following error:
[30494:30508:1110/000344:ERROR:platform_thread_posix.cc(127)] 
pthread_create: Die Ressource ist zur Zeit nicht verfügbar
[30494:30508:1110/000344:FATAL:platform_thread_posix.cc(136)] Check 
failed: handle == thread_handle->platform_handle() (140468332017408 vs. 0)
Abgebrochen

Again the error message states -- this time in german -- that the 
resource is temporarily unavailable. So no problem here.


  * When using 'ulimit -u 200' and then trying to execute any program 
from this terminal, the error message is:
bash: fork: retry: Keine Kind-Prozesse

Here it is clear, that already the bash could not fork.

So far I see no problems.

For problems with /etc/security/limits.conf:
With the following, everything works fine, but with the hard nproc limit 
of 100 uncommented, I cannot start any program in Gnome.
*       hard    maxlogins       4
#*       hard    nproc           100
*       hard    data            102400
*       hard    rss             10000
If I understand correctly, nproc limits are the same as 'ulimit -u' 
limits, so see above.

Thus I think there is no problem at all here, since it has to be 
expected that chromium cannot run without forking a bit and the error 
message state just that.
So I suggest to close this bug.

Best regards,
Andreas
