Bug Description

(gdb crashed with SIGSEGV in _IO_vfprintf_internal())

This is to duplicate an upstream bug report that affects users on both 14.10 and 14.04 LTS.

Test case:

echo 'void _ZN5Utils9transformIPN15ProjectExplorer13BuildStepListEZNKS1_18BuildConfiguration14knownStepListsEvEUlS3_E_EEN4Myns5QListIDTclfp0_cvT__EEEEERKNS7_IS8_EET0_() { } int main() {}' | gcc -xc - && gdb ./a.out

Upstream has a patch, and it'd be nice to also SRU the fix to 14.04 LTS because users are seeing it (as reported on IRC).

Thank you for reporting this bug to Ubuntu.

Ubuntu 14.10 (utopic) reached end-of-life on July 23, 2015.
Ubuntu 14.04 (trusty) reached end-of-standard-support on Apri

See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

I could not replicate that bug in currently supported versions (focal, jammy, kinetic, lunar, mantic):

$ lxc launch images:ubuntu/CODENAME tester # replace CODENAME with focal, jammy, kinetic, lunar, mantic
$ lxc exec tester bash
$ apt update
$ apt install -y gcc gdb
$ echo 'void _ZN5Utils9transformIPN15ProjectExplorer13BuildStepListEZNKS1_18BuildConfiguration14knownStepListsEvEUlS3_E_EEN4Myns5QListIDTclfp0_cvT__EEEEERKNS7_IS8_EET0_() { } int main() {}' | gcc -xc -
$ gdb ./a.out # type "quit" to exit gdb
$ exit
$ lxc stop tester
$ lxc delete tester

We appreciate that this bug may be old and you might not be interested in discussing it anymore. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in.
