SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.14.0-162.6.1.el9_1.0.1.x86_64 #1 SMP PREEMPT_DYNAMIC Mon
Nov 28 18:44:09 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
KDE Plasma Version: 5.24.6
KDE Frameworks Version: 5.96.0
Qt Version: 5.15.3
ADDITIONAL INFORMATION
Passing NULL to 2nd argument in
int setitimer(int which, const struct itimerval *new_value, struct itimerval
*old_value)
is not supported. Kernel emits warning, and
glibc on 32bit with _TIME_BITS=64 will coredump immediatedy due to
deferecencing new_value->it_interval.
The attached patch seems to fix this.
