http://bugs.winehq.org/show_bug.cgi?id=5218 Summary: Wine compiled with -Os optimization crashes Product: Wine Version: CVS Platform: PC URL: http://appdb.winehq.org/appview.php?appId=1836 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-loader AssignedTo: wine-bugs(a)winehq.org ReportedBy: phil(a)mail.ru Wine compiled with -Os optimization flag crashes when loading some native dlls. Using git bisect I've tracked it down to this recent commit: Alexandre Julliard: ntdll: Add wrappers for the string functions. http://source.winehq.org/git/?p=wine.git;a=commitdiff;h=473fbcb781a2d42dd93d 05680dfdef88999349fa +loaddll,+module,+imports log and backtrace attached. You can see from the backtrace that the top of the stack is corrupted. I tried to single-step to the crash, and it happens on a TRACE_() in fixup_imports(). When I step by single instructions, I see that it enters wine_dbg_log(a)PLT and next segfaults - I think that the relocation table or whatever this @PLT thing uses gets overwritten with ASCII data at some previous stage. When I comment out these TRACE_()s or compile without -Os, everything works fine. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
