I was using strtoul on a '2418 and it would continually reset. I dug up
the source and compared it to that of atoi, which did work. The former
used register variables:
unsigned long
strtoul(nptr, endptr, base)
const char *nptr;
char **endptr;
register int base;
{
register const char *s = nptr;
register unsigned long acc;
register unsigned char c;
....
I made a copy, removed the "register" modifiers and well, that seemed to
work. This was with an older build of the MSP430X compiler. I figured
I'd quickly recheck, and now it seems it doesn't reboot, but instead
reports the wrong values. I'm afraid I don't have time to look into that
at the moment, though.
Regards,
Michiel
