OK; that's a totally different problem than Don's. I would like to get
to the bottom of this.

0x100ab1e0 is a pretty big size. Is this reproducible ?

I'm not sure how realloc gets called as I do not believe OpenSM calls it
directly (or any of its libraries).

Are you using 32 or 64 bit libraries for this ?

Would you rebuild OpenSM with debug:
./configure --enable-debug && make clean && make && make install

and then run opensm under gdb and provide the backtrace after the
failure?

Thanks.
