This did not help but I'm getting closer. I don't have a full trace 
back but the debugger tells me that it happens in line 99 of file 
hash.c:

char *b = (*data)->key;

Since the problem vanishes when I turn off optimization (-O0), I'm not 
sure whether it is a compiler or jam bug. I will forward the problem to 
our local Cray analyst tomorrow. All I can think of right now is that 
maybe somewhere a variable does maybe not get initialized properly when 
optimization is turned on.
