[Bug 1509299] [NEW] parallel build race condition between dh_gencontrol and dh_strip

Fri Oct 23 10:35:15 UTC 2015

Public bug reported:

We observed an FTBFS of vim with the attached build log.  It seems there
are two parallel threads of dh_strip and dh_gencontrol, and they step on
each other:

Excerpt:
