https://bugs.winehq.org/show_bug.cgi?id=47751 Bug ID: 47751 Summary: x64dbg crashes in get_current_context / InterlockedCompareExchange Product: Wine Version: 4.9 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: msvcrt Assignee: wine-bugs(a)winehq.org Reporter: bernhardu(a)mailbox.org Distribution: --- While investigating on debian bug 939559 I tried to launch x64dbg and found it crash on startup already. This was with debian distribution packages of wine. I could reproduce it also with a wine built from git.

The function _CurrentScheduler__Id is tested in msvcrt110 tests, but for some reason I could not find a crash in any testbot logs, also not with a noop patch to msvcrt110. While I am seeing this issue on Debian 10, which is used by testbot too. I think the issue might be in debian build and mine, that the variable context_tls_index ends up in the .text section of msvcr120.dll.so, which might be readonly. Before the above mentioned commit that variable is in the .data section of msvcr120.dll.so. For some reason the DEFINE_VTBL_WRAPPER lines are related. Moving these to the end of the file makes the variable be again in the .data section in current git head. But as testbot does not suffer from this, I am not sure if this is an issue with my setup or compiler versions, or such. Doesn't testbot use the Debian 10 compiler versions? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
