Segmentation Fault in StatInit()

I installed ARPACK++ (from here:
http://www.ime.unicamp.br/~chico/arpack++/)and compiled it. After
installing ARPACK and SuperLU packages, I tried compiling the examples
in ARPACK++ packages.

When I try to run the exampes after they compile, only asymreg runs
successfully. But all others end with Segmentation Fault. I tried to run
them in gdb and noticed that all of them segfault in a "StatInit()"
function (see an example below).

Anybody have any idea what could be going wrong or even seen this before?

I am using gcc 3.2.

Thanks,
->HS
