EDIT: nevermind, same details :facepalm:

To make it easier you could add another DEBUG_EXCEPTION_HANDLER inside server try block https://github.com/minetest/minetest/blob/9fc018ded10225589d2559d24a5db739e891fb31/src/server.cpp#L119-L124 Debugging it that way takes some iterations but in the end will probably reveal cause, I think that's still probably best way for live server unless you can get better stack traces (one which actually includes stack trace for error instead of debugging stuff...).

{BEGIN|END}_DEBUG_EXCEPTION_HANDLER is just catch all thing https://github.com/minetest/minetest/blob/9fc018ded10225589d2559d24a5db739e891fb31/src/debug.h#L90-L98 so might need another just for bad::alloc as catch all in that try..catch block might already be too much...

I grepped the last actions just before each crash, not sure if there's a pattern though:
