Without seeing the actual code, there are two possibilities
I can think of.
The first is that something cut together by the optimizer
causes the fault, so the line info is not completely correct.
Look at the preceeding line to get an idea, or
recompile without optimization (at least that module)
and try again.
The other one is that InfoMail() returns a struct, that
is assigned to an uninitialized pointer, something like
struct bar *foo;
struct bar InfoMail(void);
foo = NULL;
*foo = InfoMail();
I am not sure if this is triggered at the end of
InfoMail() or where the actual assignment takes place,
so this may be complete nonsense.
