opm serve cache-only exits with code 139

[MikeEdgar]

We have an operator catalog build in a GitHub action that exits occasionally with code 139 [1], which appears to be SIGSEGV. The linked occurrence is for the s390x platform build, but it has also occurred for other architectures. The build is using the 1.50.0 release image from quay.io/operator-framework/opm:v1.50.0.

#14 [linux/s390x 3/3] RUN ["/bin/opm", "serve", "/configs", "--cache-dir=/tmp/cache", "--cache-only"]
#14 ERROR: process "/bin/opm serve /configs --cache-dir=/tmp/cache --cache-only" did not complete successfully: exit code: 139
