It looks like new dwz-0.13-6.fc34 is silently segfaulting when
rebuilding some srpm, but it does not prevent whole rpmbuild process
from stopping.

This might be:

   dwz crashes on DWARF5 line table with zero files
   <https://bugzilla.redhat.com/show_bug.cgi?id=1919243>

Would you please try and see if dwz-0.13-7.fc34 fixes the issue?

Looks like at least for these 2 packages, dwz is no longer segfaulting,
Thank you.

Since rpmbuild process seems to finish anyway, this can be ignored??

Historically, this is how dwz and gdb-add-index have been deployed.  The
idea is that failed debuginfo optimization do not make the package
unusuable.  (gdb-add-index crashes can lead to packaging of huge
temporary files though.)

Okay, I didn't know this, thank you.


I'm not sure if this is the right approach anymore.  If these tools
cannot process the debuginfo, the debuginfo itself might be corrupted.

Thanks,
Florian

Mamoru
