Bug ID: 47311 Summary: Heap debugging (WINEDEBUG=+heap) broken since wine-4.6-132-g948fc85186 Product: Wine Version: 4.6 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs@winehq.org Reporter: focht@gmx.net Distribution: ---
Hello folks,
apparently no one does bugs with heap corruption these days ;-)
Seems that recent Wine regressed when +heap debug channel is turned on, immediately causing abort/assert due to heap corruption.
