One likely potential cause is the fact that released FPC versions enable all floating point exceptions. Since libc does not do that, many C programs and frameworks contain invalid floating point operations. You can try adding the following to your dll: uses math; ... initialization SetExceptionMask([exInvalidOp, exDenormalized, exZeroDivide, exOverflow, exUnderflow, exPrecision]) end. Of course, this means that you won't get such exceptions in Pascal code either anymore._______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
