Please reach out to the debian-glibc team discuss these issues. The distro team
is best placed to understand the test results of Debian's glibc given the

There were no distribution or machine maintainers that did any testing for
sparc64 in glibc 2.36:
https://sourceware.org/glibc/wiki/Release/2.36#SPARC_.2864-bit.29
I'd say the sparc64 support is at risk of being removed if maintainers and
developers are not testing or supporting the architecture.

The issue is alleviated by building with "--disable-default-pie".

On sparc, where static PIE is not supported but PIE is, both libc and static
binaries are built with -DPIC. It leads to wrong startup code for static
binaries. I will send a patch.

FWIW, this issue affects sh4 as well.
Unless glibc is built with "--disable-default-pie", building a static busybox
binary on sh4 fails with the following linker errors:

Similar segfaults observed on alpha as well starting with 2.34:
> https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=alpha&ver=2.34-8&stamp=1662963628&raw=0
> https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=alpha&ver=2.35-4&stamp=1666729919&raw=0
> https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=alpha&ver=2.36-4&stamp=1667607306&raw=0
However, building with "--disable-default-pie" doesn't seem to help in this
case.

Wasn't this issue fixed a year ago? Can we close this bug?

The issue is even if static-pie is disabled for sparc64, it changes some build
flags that end up using the wrong flags on the start files build. So currently
we still require --disable-default-pie.
