Hello,

I believe I have encountered a similar/the same issue but for me it
triggers on all the architectures:

/builddir/build/BUILD/mariadb10.11-10.11.17-build/mariadb-10.11.17/mysys/waiting_threads.c:
In function ‘wt_init’:
/builddir/build/BUILD/mariadb10.11-10.11.17-build/mariadb-10.11.17/mysys/waiting_threads.c:460:5:
internal compiler error: Segmentation fault
   460 |     double to= log(60e6);  /* 1 min */
       |     ^~~~~~

The builds are here:
https://koji.fedoraproject.org/koji/taskinfo?taskID=145945213
The package still builds ok on a local mockbuild and has built ok yesterday
in koji as well.

Best regards,

Pavol Sloboda

I also see similar ICE on all arches for magic build:
https://koji.fedoraproject.org/koji/buildinfo?buildID=3002670

Looks like glibc-2.43.9000-17.fc45 which was pushed into F45 buildroot
2 hours ago is the culprit.
https://bodhi.fedoraproject.org/updates/FEDORA-2026-f9c515532f

Downloading glibc to -16.fc45 cures the ICE.
https://koji.fedoraproject.org/koji/taskinfo?taskID=145946402

Untagging needed?

Regards,
Mamoru

glibc-2.43.9000-17.fc45 is now untagged.

Hello,

I've attempted to kick out the rebuilds for new icu in rawhide which was
announced last week via
https://lists.fedoraproject.org/archives/list/[email protected]/thread/F77MAW4H5YQW67LWPNWIIPCNAFRXBOP7/
(that is on hold for now).

I however encountered lots of compiler fails on both s390x and i686 (eg.
boost scratch build at
https://koji.fedoraproject.org/koji/taskinfo?taskID=145945327 , but this
is plaguing many more packages):

/usr/include/c++/16/cmath: In instantiation of ‘_Tp
std::__detail::__ellint_rf(_Tp, _Tp, _Tp) [with _Tp = float]’:
/usr/include/c++/16/tr1/ell_integral.tcc:201:27:   required from ‘_Tp

*/usr/include/c++/16/cmath:384:26: internal compiler error: Segmentation

  ~~~~~~~~~~~~~~^~~~~~~~~~*

These are present even in attempted scratch builds outside the icu
side-tag, so that isn't the culprit. Does anyone have any more context/can
look into it?

Thanks!
