The crash is stackoverflow. Improving reporting of stackoverflows is tracked by #72920 .

The actual problem is that the default stack on Alpine is too small. Looks like the following is not getting defined:

runtime/src/native/libs/System.Native/CMakeLists.txt

Line 7 in 0a47ab0

if (CLR_CMAKE_HOST_ALPINE_LINUX)

.

Can't repro this on my WSL with Ubuntu 20.04.06 LTS though, tried both Release and Checked

Ah, it explains why I can't repro it, my ulimit is:
