https://bugs.winehq.org/show_bug.cgi?id=49834 Bug ID: 49834 Summary: 45a63e5b3ce0e5d7fcc55ce57f315086b87f8ad7 breaks binary compatibility with 5.0 on passing main() argc Product: Wine Version: 5.9 Hardware: x86-64 OS: Linux Status: NEW Keywords: regression, source, testcase Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: dmitry(a)baikal.ru CC: julliard(a)winehq.org Regression SHA1: 45a63e5b3ce0e5d7fcc55ce57f315086b87f8ad7 Distribution: --- Created attachment 68172 --> https://bugs.winehq.org/attachment.cgi?id=68172 test winelib module (source + binary) I have a private winelib module compiled with stable wine-5.0.2 branch. Recently this module was broken after upgrading Wine. I've attached test with source and pre-compiled binary using wine-5.0.2. When running with wine-5.0.2 it looks like this: $ wine test.exe.so Starting (argc = 1, argv = 0x113120)... Done. $ wine test.exe.so -v Starting (argc = 2, argv = 0x1132e8)... verbose is on Done. When running with wine-5.17 argc passed to main() is no longer valid, which makes the app try to parse not existing command like arguments: $ wine test.exe.so -v Starting (argc = 3, argv = 0x143a10)... verbose is on Done. $ wine test.exe.so Starting (argc = 2, argv = 0x110f48)... wine: Unhandled page fault on read access to 00000000 at address 7ECF30AF (thread 0024), starting debugger... couldn't load main module (2) Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x7ecf30af).
