mkdwarfs 0.5.0 crashes at creating images

[Kron4ek]

Unlike the previous time, now it crashes with any compression level.

** Aborted at 1617652815 (Unix time, try 'date -d @1617652815') ***

mkdwarfs-0.5.0-coredump.zip

This is with the static 0.5.0 binary from the releases page. Manually compiled dynamically linked build works fine.

Thanks again for the report!

I wish I had one of those CPUs for testing...

This time it's not as obvious as before. The routine in which it crashes is not fancy at all. I reckon the crash goes away if you specifiy --pack-metadata=none.

Could you please try this version that's built with gcc instead of clang? mkdwarfs-0.5.0-gcc.gz

Ah, don't worry about testing the new binary (it likely won't work), I think I've found the issue. A new library I'm using sets -march=native in its Makefile and that's obviously a bad idea for statically linked binaries...

[Kron4ek]

The new binary crashes too. And you are right, --pack-metadata=none fixes the crash.

Okay, could you please give mkdwarfs-0.5.1pre.gz a try before I'm pushing a new release?

[Kron4ek]

This build works without issues, thank you.

Thanks for your help! New release is out.
