[Bug 54482] New: RtlCaptureStackBackTrace cause segv
https://bugs.winehq.org/show_bug.cgi?id=54482 Bug ID: 54482 Summary: RtlCaptureStackBackTrace cause segv Product: Wine Version: 8.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: ake.rehnman(a)gmail.com Distribution: --- Created attachment 74033 --> https://bugs.winehq.org/attachment.cgi?id=74033 patch attempt RtlCaptureStackBackTrace crash on segmentation fault because the unwinding keeps going beyond the stack end. It seems on x86-64 the stack actually starts at least 32 bytes below StackBase so the compariston with context.rsp to StackBase will never hit but we get a context.rpc value of 0 which obviously SEGV:s. I made a patch attempt and just check if rcp = 0 and end the unwinding. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
