[Bug 43666] New: PuTTY crashes if compiled with 64-bit winegcc ( winegcc defines va_list incorrectly for Win64)
https://bugs.winehq.org/show_bug.cgi?id=43666 Bug ID: 43666 Summary: PuTTY crashes if compiled with 64-bit winegcc (winegcc defines va_list incorrectly for Win64) Product: Wine Version: 2.16 Hardware: x86 OS: Linux Status: NEW Severity: normal Priority: P2 Component: tools Assignee: wine-bugs(a)winehq.org Reporter: alexhenrie24(a)gmail.com Distribution: --- Created attachment 59112 --> https://bugs.winehq.org/attachment.cgi?id=59112 backtrace To reproduce this bug: 1. Clone PuTTY from https://git.tartarus.org/simon/putty.git 2. Run `./mkfiles.pl` 3. Run `make -C windows -f Makefile.mgw CC="winegcc -mno-cygwin" COMPAT="-D__MINGW32__" RC=wrc` 4. Run `wine windows/putty.exe.so` A backtrace is attached, but to save you some time, PuTTY is crashing in its dupvprintf_inner function: va_list aq; va_copy(aq, ap); len = vsnprintf(buf + oldlen, size, fmt, aq); va_end(aq); The problem is that va_list has one ABI on 32-bit Windows or Linux binaries and another on 64-bit Windows binaries. I can work around the problem by adding -m32 or -mabi=ms to the winegcc options. One solution might be to make winegcc use -mabi=ms by default. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
