Hello everyone,

Assuming that backport has been merged for few days now,  is there a chance that 14.2.13 will be released? >

On the dev list it was posted that .13 will be released this week.

    Jason/Wido, et al:
          I was hitting this exact problem when attempting to update
    from 14.2.11 to 14.2.12.  I reverted the two commits associated with
that pull request and was able to successfully upgrade to 14.2.12. Everything seems normal, now.


    Thanks,

    This backport [1] looks suspicious as it was introduced in v14.2.12
    and directly changes the initial MonMap code. If you revert it in a
    dev build does it solve your problem?
