Hello,
I was wondering on how other gnu programs handle integer overflows.
I've recently modified libtasn1 to detect those, but it seems
that a portable overflow check is cumbersome to use and inefficient
(requires an additional division to perform a multiplication). Have you
seen different/simpler approaches to this issue?

regards,
Nikos
