Bug ID: 39449 Summary: __finally being called too many times Product: Wine Version: 1.7.52 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: lamberga@gmail.com Distribution: ---

This bug dealing with exception handling only occurs in a 64 bit environment. Appears to be independent of msvc*.dll version (also, switching to native dlls does not seem to have any effect). I have attached a reproducer.

Expected output (output under Windows and 32 bit Wine): Hello from main Hello from prog1 Finalizing Caught: Oh No!

Output under 64 bit Wine: Hello from main Hello from prog1 Finalizing Finalizing Caught: Oh No!

--- Comment #2 from Sebastian Lackner sebastian@fds-team.de --- Could you maybe provide a precompiled executable of your test code? I would like to reproduce this issue, but don't have a 64-bit version of the MS build tools available.

--- Comment #7 from Sebastian Lackner sebastian@fds-team.de --- The problem is that RtlUnwindEx is called from within a STATUS_UNWIND_CONSOLIDATE callback, it should skip already unwound stack frames. On Windows this is solved with specially crafted unwind info in a wrapper function. I'll see if I can come up with a solution for this.
