Hmm. Because the other way this could be addressed is to fix gdb. (1) it shouldn't crash and (2) it could support elf alongside pe-coff fairly easily i'd imagine; just a matter of enabling that bfd backend. Shall we ask gdb maintainers? r~ ^ permalink raw reply [flat|nested] 4+ messages in thread

For the w64 port of gdb, I needed a quick solution. Usually it will take some time to ask the gdb maintainers, find a solution, get distributions which include the solution and use such distributions everywhere. I don't think that the setup with pe-coff (when it is supported) will be 100 % identical to the elf setup, so most probably we'll need a test for ELF / not ELF anyway. Therefore I suggest to apply my patch, even it is only an intermediate solution for the next year. Regards, Stefan W. different ^ permalink raw reply [flat|nested] 4+ messages in thread
