system info
0xc0000005 is not related to Win 7. Have same problem, it's always crashing silently on HEVC encoding, Windows 11, i9 14900K, sometimes after a few minutes, sometimes after hours of encoding.
-report option doesn't show any additional information.
Switched to BtbN ffmpeg builds and all problems are gone. The only difference I see is gcc 13.2.0 - MSYS2 vs gcc 14.2.0 - crosstool. Can be one more gcc 13.2.0 optimization bug...

Which build and version?
The last build I tested was ffmpeg-2024-09-19-git-0d5b68c27c-full_build.7z but the same happens with all builds I tried in the last ~2 months, including latest 7.0.2 release build.
Yes, it still happens. Log attached

Someone's reported a crash with the same exception code with a BtbN build (gcc 14.2.0) . Since no one's reported it (yet) with an essentials build, I suspect some change in an external library.
For proper debugging, I'll need a minimal reproducible command (and assets, if it matters).
Testing both builds on new ASUS BIOS with "Intel microcode update 0x12B for its 13th and 14th generation Core processors, addressing persistent stability issues stemming from voltage irregularities". Will let you know about results.
5 days of testing, no any crashes so far, So it looks like in my case it was unstable CPU.
