(I also, believe it or not, want to catch EXC_ARITHMETIC, which doesn't seem to get mapped to SIGFPE) At least on Mac OS X, the init code of libc doesn't turn on (or possibly explicitly turns off) all FPU exceptions. If you turn them on, you can catch SIGFPE's as much as you like. Especially when you have a GUI program and turn on "invalid fpu operation" exceptions, since there's a bug in CoreGraphics since 10.4.0 that triggers this exception on some systems when drawing certain font ligatures (there's a radar on this somewhere, but not by me since it doesn't happen on my systems).
