This can happen with asynchronous decoding, such as with the VA-API decodebin plugin for H264.

Since struct _IAVIStreamImpl has a pointer to a WAVEFORMATEX, GCC 12.2 emits warning when dereferencing that pointer when the block has been allocated with sizeof(PCMWAVEFORMAT). The warning is fixed by always allocating with sizeof(WAVEFORMATEX). This will overallocate in case of a PCM stream. The alternative would have been to store in struct _IAVIStreamImpl a pointer to PCMWAVEFORMAT instead, and add the casting to a WAVEFORMATEX when needed. That would clutter the code IMO since most of the ACM APIs expect a LPWAVEFORMATEX. /home/eric/work/wine/dlls/avifil32/acmstream.c: In function 'AVIFILE_OpenCompressor': /home/eric/work/wine/dlls/avifil32/acmstream.c:105:24: warning: array subscript 'struct tWAVEFORMATEX[0]' is partly outside array bounds of 'unsigned char[16]' [-Warray-bounds] 105 | This->lpOutFormat->wFormatTag = WAVE_FORMAT_PCM; | ^~ /home/eric/work/wine/dlls/avifil32/acmstream.c:101:27: note: object of size 16 allocated by 'HeapAlloc' 101 | This->lpOutFormat = HeapAlloc(GetProcessHeap(), 0, This->cbOutFormat); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Eric Pouech <eric.pouech@gmail.com>

ntdll: Keep pagemap file open after first use of NtQueryVirtualMemory(MemoryWorkingSetExInformation).

1 syscall instead of 2 syscalls. Faster and simpler code.

Legends game periodically (every 30 seconds) calls this function with up to 22k virtual addresses. All but 1 of them is valid. Due to amount of queries addresses, and cost of seek+read, this causes this function to take up to about 50ms. So framerate drops from ~150 FPS to 20FPS for about a second. As far as I can see, returning 0 entries from this function, still makes Apex Legend work. But keep code correct, and optimise it by only performing pagemap read when the address is valid. This change get_working_set_ex reduces peek wall clock runtime from 57ms to 0.29ms. Tested on Linux, but similar change done for the BSD part. Signed-off-by: Witold Baryluk <witold.baryluk@gmail.com>
