Howdy,

This problem is urgent as it produces unstable system modifications.

This system is F45 (rawhide) x86_64.

During various system operations, a call to pkgconf hangs with 99.9% cpu utilization. "strace -xvfp " shows NO system calls being made. Top reports 99.9% cpu utilization."gdb -p " responds to a "where" command and produces a stack trace (below). Failures during build of software such as htop and make have been observed as well as kernel upgrades which has produced an unbootable system.

There appear to be no error messages to any logs.

This problem is rather urgent; PLEASE help.

Best regards,

George...
