92 (buf) + 4 (f1) + 4 (bfp) = 100
The extra eight is presumably optimization padding for pending calls. However, I'm not definite on that, since, I don't run GCC3 and can't currently view the generated asm to say that is likely.
An older version (2.95.3 on NetBSD) seems to consistantly add 20 octets. So, maybe it is just bad programming on the part of the GNU team.
