The fpu emulation is buggy in with kqemu, it's even worse with kernel-kqemu. no easily detected failures with no-kqemu. I wrote a tool to detect misbehaving cross-compilers for people building gpsd to use in embedded system; it will also complain about kqemu. Perhaps debian is slightly more tolerant of fpu errors, but if you watch closely, you'll see fallout from math errors under ubuntu (progress bars look like line noise) and winxp (programs don't reliabily start, and all menu bars render as 1px high... -- GDB has a 'break' feature; why doesn't it have 'fix' too?
