Issue with using action=2 (BOBYQA)

[AvivTheMan]

When running the minimizer with action=2 in the CosmoMC May 2020 release (for example, on the Planck 2018 data or BAO compilation), it crashes every time with output similar to:

Caught signal 11 (Segmentation fault: address not mapped to object at address (nil))

The stack looks like:

I've seen this issue appear in CosmoCoffee (https://cosmocoffee.info/viewtopic.php?t=3207); however, the fix to camb/fortran/ mentioned near the end seems to already be implemented, yet it still results in the above error.

Any help would be appreciated. Thanks!

Sorry I don't know what causes this, if you figure it out a pull request would be welcome. Otherwise you can try using the same function Cobaya.
