Description

Version 0.71.0 of Flux does not parse spindle options correct in two cases. This case causes a segfault:

flux run \
    -o userrc=${FLUXRC} \
    --tasks-per-node=3 \
    --nodes=3 \
    python3 --version

The workaround is to add -o spindle.

This case causes an error:

flux run \
    -o userrc=${FLUXRC} \
    -o spindle \
    -o spindle.python-prefix=/usr/bin \
    --tasks-per-node=3 \
    --nodes=3 \
    /bin/true

The workaround is to remove -o spindle.

The underlying issue is how Flux was setting up option tree. The fix is described here. Hopefully that will be rolled into the 0.73.0 release.

This issue is a reminder to test these conditions once 0.73.0 shows up on local machines.

These issues are not at all critical and don't warrant downloading and building a one-off version of flux for testing.

Research direction

No repository file or test is named. When Flux 0.73.0 is available locally, run the two flux run command cases from the issue, using issue 6678 for context; done means recording whether both invocation patterns work without their former workarounds.
