I tried the attached patch, and it works, but brings back the bug I referenced for 32-bit. > Also, I noticed in objdump that the Delay import directory entry in the > optional header is 0.

Right now, it is put into .text$2, which seems like a hack for the fact that putting it into .idata$2 would have messed up the normal import directory. I am confused by what LLD is doing though. It is putting the functions and modules into .data, and the read-only stuff into .didat. The way I read the docs suggested to use .didat to hold the function pointers so that the guard flags could allow the OS to change protection as needed without affecting other data. _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
