Comment(by pv):

 Getting a SIGILL out of wrong numerical values seems quite unlikely to me.
 The exception means that the CPU encountered an *instruction* that it does
 not understand, which should not happen if only the data is wrong.

 @Ralf, are you 100% sure that the NOSSE binaries really have no SSE2
 instructions in them? This can be checked by running a disassembler on the
 dll's. A script doing that (on UNIX) is attached, but I guess objdump is
 available also on Windows.
