A child process is being killed.

The output of strace -f would be more helpful.

Partial strace output

Full output too large to attach even xz'd so here is a chunk from the end, hope it's sufficient.
Comment 4 Phil Stracchino (Unix Ronin) 2023-01-01 19:47:52 UTC
I can also reproduce this, with sys-apps/man-db-2.11.1 ...  on one system out of four, and damned if I can figure out what is different in software on the one system where it is failing that is causing it to fail.  I mean, the three systems that it works on are servers, and the one where it doesn't is my desktop workstation, but all of the software differences involved in that are WAAAAY above the level of anything that should be able to impact anything as low-level as 'mandb -q'.  The core system on all four is *intentionally* as nearly identical as I can make it.

The only plausible thing I CAN pick out as unequivocally different is at the hardware level:  all three servers are Intel-based Dells (an R720 and two R610s), while the desktop is AMD-based (Phenom-II, Thuban microarchitecture).

I think report it upstream at https://gitlab.com/man-db/man-db/-/issues & link it back here.

Thanks. Fixed in 2.11.2.
