Yes, the Pentium 4 should have SSE. You can verify this by looking at the flags

I don't think it is SSE related at all.
Try running the following program in gdb:
int main()
{
int abc = 2, bcd = 0;
abc /= bcd;
return 0;
}
it should give you the very same error.
I am guessing that the _mesa_test_os_sse_exception_support () function is
testing arithmetic/floating point exceptions, but when you run under gdb, gdb
will intercept for example the SIGFPE signal (Floating Point Exception) instead.
