[geos-devel] SIGABRT in GEOS using the C-API

[Alex Trofast]

Greetings all, I'm getting a SIGABRT in GEOS, but not on all Linux distros. The following is a partial backtrace from Ingres:
Program received signal SIGABRT, Aborted.

The platform is Fedora 12 64 bit, but it also occurred on Fedora 13 64 bit. It did not occur on Arch Linux 64 bit or Fedora 11 32 bit. It also does not occur on Windows 32 bit as far as I can tell. Does anyone have any idea why this might be happening? Any help is greatly appreciated!

Thanks

Alex
