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/devel@lists.fedoraproject.org/... (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 std::__detail::__comp_ellint_1(_Tp) [with _Tp = float]’ 201 | return __ellint_rf(_Tp(0), _Tp(1) - __k * __k, _Tp(1)); | ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/c++/16/bits/specfun.h:358:44: required from here 358 | { return __detail::__comp_ellint_1<float>(__k); } | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~ /usr/include/c++/16/tr1/ell_integral.tcc:102:40: in ‘constexpr’ expansion of ‘std::pow(1.1920929e-7f, 1.66666672e-1f)’ 102 | const _Tp __errtol = std::pow(__eps, _Tp(1) / _Tp(6)); | ~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
*/usr/include/c++/16/cmath:384:26: internal compiler error: Segmentation fault 384 | { return __builtin_powf(__x, __y); } | ~~~~~~~~~~~~~~^~~~~~~~~~*
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!
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,

I've managed to reproduce the boost ICE on i686, but it is really weird. The ICE is within mpfr: #0 0x00000000 in ??

In rawhide, glibc copies the TLS initialization image before relocation, so pointer initializations are lost. Adhemerval has already posted a fix:
[PATCH] elf: Re-initialise static TLS after .tdata relocation (BZ 34164) https://inbox.sourceware.org/libc-alpha/20260526185235.4093779-1-adhemerval.zanella@linaro.org
The v2 version merely adds a bug reference.

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?
