I found the correct ulimit setting to enable core dumps, and was able to
use that to obtain a stack trace - see attached.
According to gdb, the failing function call is this memcmp(), called
from svn_dirent_skip_ancestor().
1440 if (0 != memcmp(parent_dirent, child_dirent, len))
1441 return NULL; /* parent_dirent is no ancestor of child_dirent */
The string arguments are evident from the stack trace.
parent_dirent=0xb47faeb0 "/auspar/trunk/Modules/VirtualShip/Trunk/RadarGeometry/RadarGeometryManager/Trunk/Test/TestApplication/Build/Win32-x86-MULTI/DevelopmentShared.gpj"
child_dirent=0xb468ef80 "/auspar/trunk/Modules/VirtualShip/Trunk/RadarGeometry/RadarGeometryManager/Trunk/Test/TestApplication/Build/Win32-x86-MULTI"
len == 147
Strangely enough, parent and child seem to back back to front. I am
assuming the memcmp is running off the end of child_dirent, and causing
my failure.
This was built with gcc 4.6.3-1ubuntu5, using '-O2 -g'
I will try setting a breakpoint here, and looking for a consistent
pattern.
