on win32 with MinGW i've had pd crash with 'bad instruction' errors by compiling with -march=athlon or i686, running on a Celeron II 500 (Coppermine). it is praobly either a bug in the audio interface code, or the aggressive optimization flags from Hans that caused the bug that started this thead..

-march=i586 -O2

is probably a good compromise. ive heard of -O3 causing problems, and -march implies -mtune and other stuff so its unnecessary to specify

best,
