Re: [PATCH v8 0/2] MR7539: combase : clsid_from_string_reg() add read of CurVer key value.
by Nikolay Sivov (＠nsivov) 10 Sep '25

10 Sep '25

This needs some work still. All places using clsid_from_string_reg() has to be tested, tests should pass on every commit, buffer sizes should likely be revised, following CurVer chain tests are incomplete. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7539#note_115539

[PATCH 0/1] MR8944: Draft: winedbg: Reserve memory according to the debug information (ASan).
by Bernhard Übelacker (＠bernhardu) 10 Sep '25

10 Sep '25

This is a first attempt to reserve more than the sizeof(DWORD). As far as I see the size in memory_read_value originates from a call to types_get_info(TI_GET_LENGTH). Therefore trying here to use a similar call to get the size for memory reservation. And if that fails, falling back to at least sizeof(void*).
