Hi,
Please send your questions to the mingw-w64 mailing list: there are a lot
more knowledgeable people there (I really only build the stuff). I have
added them to the CC list.
As to your problem: I have no idea, sorry.
Could someone please take a look? I have attached the output he is getting
for 32-bit executables in 32- and 64-bit gdb. he sent me this off-list. The
rest of the discussion is below.
Thanks,
Ruben
