[GE users] DRMAA Segmentation Fault

Hi

I have experienced segfaults with the drmaa C library, which is what the 
java library uses.

In my case it was calling drmaa_exit before calling drmaa_init that 
caused the seg fault. I'll file a bug report, once I've carried out some 
more tests.

Could this explain your program's behaviour? For example, are you 
calling any functions out of sequence?

cheers
