I am attempting to compile the latest version using codeblocks and MingW and am having some problems with the assembly code in as_callfunc_x86.cpp. The error log looks like this:

I have no experience with assembly so I can't make heads or tails of the code itself. Thanks for working so diligently on this project, it is an extremely useful piece of software.

I'll see if I can figure this out. Though I feel it is strange that MinGW complains, because this very same file is compiled properly on Linux and Mac using GnuC (which as far as I know is practically that same as MinGW).

Thanks for reporting it.

I had this with older Angelscript versions too, when I was compiling with -O3. Switching to -O2 (less optimization), solved the problem then.

Thanks for reminding me DaBono. This is indeed the fix that I remembered.

Setting the optimization back to -O2 fixed it.

I really like this scripting engine, the only problems I have had with it are of my own creation, and I am very interested in the implicit casting updates.

Does someone know how to tell the gcc compiler not to inline the functions? I think this is what causes the problem when compiling the library with -O3 optimization.
