| I have examined the two DLLs with nm and found substantial differences in runtime support functions. VL'sx DLL uses setjump-longjump ("sjlj") type exception handling, my DLLs use Dwarf2 ("dw") style exception handling.
This may be the cause of the problem.
Also, the "Atom" functions are defined in the VL DLL.
There are other differences.
All the opcode functions in the two DLLs, on a hasty look, are the same.
My best guess at this time is the exception handling code is the reason DLLs built by VL's version of GCC are not compatible with binaries built with my version of GCC. This should not matter because these DLLs are loaded at run time -- correct? But it seems to anyway.
I still do not see why my DLLs should not work with the 5.08 binaries, but I did upgrade GCC again after building 5.08, so that is probably it.
If this is an urgent issue for you, I can build the installer and FTP it to a site where you can download. Still no guarantees of course. Otherwise, we should have a 5.09 version in a month or so.
Another option is for me to switch to the setjump-longjump version of the current MinGW compiler.
Regards,
Mike

The optimization may be why nm does not show the cos() function in the code, although it is there in the source code -- it may be inlined or intrinsic or something.
