It contains workarounds to several common problems. In particular, if Valgrind aborted or crashed after identifying problems in your program, there's a good chance that fixing those problems will prevent Valgrind aborting or crashing, especially if it happened in m_mallocfree.c. If that doesn't help, please report this bug to: www.valgrind.org In the bug report, send all the above text, the valgrind version, and what OS and version you are using. Thanks. Note, I only had wine-staging 2.17 installed, I can retest in 2.20 if needed. I havne't filed a valgrind bug, as it seems more likely to be a staging bug, but I can file one upstream if needed. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=43352 Bug ID: 43352 Summary: dlls/kernel32/tests/virtual.c has an infinite loop under valgrind Product: Wine Version: 2.12 Hardware: x86 OS: Linux Status: NEW Keywords: download, source, testcase, valgrind Severity: normal Priority: P2 Component: kernel32 Assignee: wine-bugs(a)winehq.org Reporter: austinenglish(a)gmail.com Distribution: --- May be related to bug 28816, but this one appeared more recently. Haven't attempted to bisect, but when running the valgrind wine tests, dlls/kernel32/tests/virtual.c enters an infinite loop, spewing: err:seh:segv_handler Got unexpected trap 0 virtual.c:2257: Test failed: NumberParameters is 0 instead of 2 virtual.c:2258: Test failed: ExceptionCode is c000001d instead of STATUS_ACCESS_VIOLATION or STATUS_GUARD_PAGE_VIOLATION err:seh:segv_handler Got unexpected trap 0 virtual.c:2257: Test failed: NumberParameters is 0 instead of 2 virtual.c:2258: Test failed: ExceptionCode is c000001d instead of STATUS_ACCESS_VIOLATION or STATUS_GUARD_PAGE_VIOLATION err:seh:segv_handler Got unexpected trap 0 virtual.c:2257: Test failed: NumberParameters is 0 instead of 2 virtual.c:2258: Test failed: ExceptionCode is c000001d instead of STATUS_ACCESS_VIOLATION or STATUS_GUARD_PAGE_VIOLATION endlessly. Note that I run valgrind with 4a1629c4117fda9eca63b6f56ea45771dc9734ac0 reverted: Revert "ntdll: Avoid possible deadlock by using _exit() in NtTerminateProcess." This reverts commit 4a1629c4117fda9eca63b6f56ea45771dc9734ac. It breaks wine + valgrind, see https://bugs.winehq.org/show_bug.cgi?id=39097 I reverted the revert, but no change. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
