--- Comment #6 from Roman Pišl rpisl@seznam.cz --- Created attachment 70233 --> https://bugs.winehq.org/attachment.cgi?id=70233 Fix for clang address sanitizer
Since 0ec555e58ea9d5b33f4c825e96965ad0cb15d00f the problem with virtual address space is fixed and the only remaining issue is function interception. I doubt the Wine goal is to have exactly same preambles on all functions as on Windows so this is probably a NOT OUR BUG and the fix should be made on clang side. I'm attaching a fix that works for me. The only caveat on Wine side so far is msvcrt/ntdll.strrchr. Clang needs 6 bytes for jump but there is a loop into ntdll.strrchr+2. Either DECLSPEC_HOTPATCH or adding 'if (c == '\0') return strchr(str, '\0');' to the beginning of the function fixes this. Hopefully this can be useful for someone.
