Not sure if this is appropriate for the GCC list, or the binutils list, but I thought I'd try here first since gnatdll is part of the GNAT toolchain. I have found that if I make the base address of the DLL produced by gnatdll (on x64 PE) higher than 0x110000000 (via the -b option), I get crashes when running applications built against this DLL. Also of note - the default base address of 0x11000000 seems pretty low, considering the Visual Studio documentation says the default base address of a DLL on x64 is 0x140000000. I can try to make a simple reproducer. Operative word here is try - I find these kinds of issues are really difficult to reproduce when one tries to simplify things. Does this sound like a GCC issue? I am guessing not, since the underlying tools for making a DLL (aside from gnat1 to produce object code from Ada source) are from the binutils kit. Should I take this to the binutils list? Thanks, Tom
