[OGo-Developer] gsmake2 branch segmentation fault

[Will Hawkins]

Good afternoon!

I have been working to get an installation of Ogo using the gsmake2
versions of SOPE and OGo. I am able to get the software installed and
running. I can log in to the Web Interface. However, the action taken
immediately after log in causes the ogo-webui to restart. I have the
following backtrace from the process in gdb:

#0  0x00000000 in ?? ()
#1  0x01088b35 in -[NSAutoreleasePool emptyPool] (self=0xb93a780,

I have attempted to debug this but after almost two days I am no closer
to the source. In the emptyPool function he segmentation fault occurs
because imps[hash] is zero (NSAutoreleasePool.m:405) for the object
being deallocated from the pool in that iteration.

If I put a conditional around that line of (ie, if (imps[hash])) the
segmentation fault occurs further down in the objc runtime. I realize
this is probably *not* a problem with the objc runtime, but I was unable
to see any other cause for this further up in the OGo code.

I have seen this bug after having installed gnustep-startup-0.18.4 and
with gnustep-startup-0.19.2. The line number reference above is for
version 0.19.2.

If there is anything else I can do to debug this problem please let me
know. I am very interested in getting to the bottom of this but I seem
to have hit a roadblock. Any information you can share would be very
helpful!

Thanks in advance,
Will
