Looking at this function (_ksig_init()), it's pretty short and I don't
see how it could cause a seg fault. :-\
Can you recompile LAM with debugging enabled (i.e., a CFLAGS containing
-g) and try to replicate this error again? I'd like to know the exact
line number that this seg fault is occurring on, and what the values of
the supporting variables are.
