Anyone noticed strange signals (segfaults?) delivered to processes in latest Rawhide in Koji?

[Richard W.M. Jones]

Always the same process (ocamlopt.opt) and always on 32 bit only.

The thing is, it *didn't* happen just 3 days ago.  Nothing has changed
in the package, and ocamlopt.opt is the same as 3 days ago.

glibc has had a few memory-related fixes in the past 3 days:
  - Revert patch for BZ696143, it made it impossible to use IPV6
    addresses explicitly in getaddrinfo, which in turn broke
    ssh, apache and other code. (#808147)
  - Avoid another unbound alloca in vfprintf (#841318)
  - Remove /etc/localtime.tzupdate in lua scriptlets
  - Revert back to using posix.symlink as posix.link with a 3rd
    argument isn't supported in the lua version embedded in rpm.
  - Revert recent changes to res_send (804630, 835090).
  - Fix memcpy args in res_send (#841787).

Has something changed in Koji or mock such as inherited signal masks?

I even went as far as building a 32 bit Rawhide VM to test this, but I
can't reproduce it there, and that's pretty odd considering it happens
reliably in Koji.
