What could be the reason for it? Anyone use Sparc64 GLibc in Qemu?

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
We have a longstanding issue where static build fails when glibc is built for
static-pie (check https://sourceware.org/bugzilla/show_bug.cgi?id=29575). Could
it be related (not sue if init is static built)?
There is some couple week since I checked sparc, but I haven't see any more
regressions than the usual ones.

I checked with Buildroot and that is working. I don't understand while my cross
toolchain does not generate working binaries. I tried a static hello world as
init and get a segfault. I am now trying to debug this hello world on a
Buildroot system, but have some issues with gdb. In parallel I am installing
Debian in Qemu and updating it to latest.

Okay, you are right. I added --disable-static-pie to glibc configure and now it
is working! Thanks.
