Package: libc6
Version: 2.42-10+b1
Severity: important
Dear Maintainer,
with the latest version 2.42-10+b1 of libc6* package on Debian/testing amd64,
there is an issue to compile some C code with tcc compiler using
/usr/lib/x86_64-linux-gnu/crt1.o file.
In this file, there is 2 conflicting sections for ".note.GNU-stack": one with
NOTE(7) type and one with PROGBITS(10) type.
$ readelf -S /usr/lib/x86_64-linux-gnu/crt1.o
There are 15 section headers, starting at offset 0x370:
