[mercury-users] Re: Mercury program loops for ever with rotd-2003-02-23

Correction: the program does not loop for ever, but actually crashes in an
unrelated function in another module which appears to be passed a NULL
pointer for some reason.

Again, the problem disappears if the call to my_function is hoisted out of
the if statement.

Trying to track down where the NULL pointer is coming from is a bit
difficult in the asm_fast.gc grade, as there is no decent stack trace in
gdb. Any tips?

Cheers,

Michael
