Re: State of Windows x64 COFF support?
Implementations can have bugs, probably COFF support wasn't stress tested.

I watched the section names and discovered over 20,000 sections named : .debug$S According to the code, a new .debug$S section is created every time it is searched with the flag IMAGE_SCN_LNK_COMDAT in: https://github.com/D-Programming-Language/dmd/blob/de6fccf8391b1dfdb959fa0f089920c2c8e6aff8/src/backend/mscoffobj.c#L1724 I deleted this flag and now the program links correctly with COFF with 50k sections. It would have been easier to debug with an error in mscoffobj.c:1591: assert(scnhdr_cnt 65536, Too many symbols for COFF format); https://github.com/D-Programming-Language/dmd/blob/de6fccf8391b1dfdb959fa0f089920c2c8e6aff8/src/backend/mscoffobj.c#L1591 With this simple patch on the compiler, there are stil some errors compiling Botan on win64, but they are not related to the COFF format anymore.

State of Windows x64 COFF support?
I'm having corrupt symbol table errors on a Win64 build of a big application, I can't find a way around it. I'm wondering if the COFF support is still experimental in DMD? Thanks!
