Indeed, I am working with LAM v7.1.2 on a Etch Debian box (intel Pentium M):
my LAM is the one distributed by Debian.

My trouble can be reproduce with the sphere C source file cited below.
If I do
gcc -o sphere sphere.c $(pkg-configure gts --cflags --libs) -lm
then I obtain an executable that works.
Bu, if I compile with mpicc instead:
mpicc -o sphere sphere.c $(pkg-configure gts --cflags --libs) -lm
then I get an executable which give me only `Floating point exception'.
I tried with both the options -fexception and -fno-exception but
I get the same error message.
I used the GTS (gts.sourceforge.net) packages distributed by Debian.
Just before to receive you email,
my plan was to make a static linking rather that a dynamic one:
may this resolve the issue.
Thanks in advance,
Jerome
