[PATCH 00/10] Fix segfaults when using the unsafe SHA1 backend

Hi,

this patch series fixes two segfaults when using the unsafe SHA1 backend. The segfaults are caused by us mixing safe and unsafe variants of the API. As such, it only surfaces when actually building Git with an unsafe backend that is different from the safe one.

I noticed those errors while wiring up the build option in the Meson build system. As such, this patch series doesn't only fix the segfaults, but also includes patches for the Meson infrastructure and is structured as follows:

  - Patches 1 and 2 fix the segfaults.

  - Patch 3 makes the segfaults visible via our CI.

  - Patches 4 to 10 wire up the build infrastructure in Meson.

Given that we're close to the release of Git v2.48 I'd be fine with merging just the first three patches. I can then re-send the Meson stuff early in the next development cycle.

Thanks!

Patrick
