https://bugs.winehq.org/show_bug.cgi?id=36511 --- Comment #1 from Austin English <austinenglish(a)gmail.com> --- This is with clang 3.4. I see that 1.7.17 (mostly) worked with clang 3.3 in bug 36079. I tried building 1.7.17 with 3.4, but it fails the same as here, in widl. I'll try bisecting clang if time permits, but presumably it's an improvement in its undefined behavior detection. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

I'm not sure what's responsible for the regression :/. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Works for me using wine-8.10. is this still relevant?
What compiler are you using? Testing on a cfarm node (gcc186), it works for me with gcc (gcc (Debian 10.2.1-6) 10.2.1 20210110), but not clang (9/11/13) using wine-8.12-136-g94d61d1b280. Side note: with gcc, it later fails in ntdll, do you see that as well? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Not sure what exactly is different now, but I now get various errors... -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Using gcc 13.1.1 20230429 export ALLFLAGS="-g -O0 -fcommon -fsanitize=undefined" with --without-mingw I get basically the same errors. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
