387 (FPU) code generation seems to be broken in gcc 3.2.1 when -O2 is used. I can compile applications with no problems when -mfpmath=sse is added so that the 387 unit won't be used, but without it, applications crash. Note that since SSE support is enabled by the kernel, it probably wouldn't be a good idea to compile the kernel with -mfpmath=sse.
