Dear Maintainer,
Starting from version 2.10.10+ds1-1 (2.10.8+ds1-1 was OK), one of the
build-time tests of openturns started to fail: t_Bonmin_std. Running it with
gdb I get:
------------------------------->8--------------------------------
(gdb) run
Starting program:
/build/openturns-eQ5lBV/openturns-1.20/builddir/lib/test/t_Bonmin_std

which indicates a problem in coinor-cbc.
The above backtrace is somewhat reminiscent of the one of the issue
https://github.com/coin-or/Cbc/issues/591
which has been fixed in upstream version 2.10.10. I suspect a close issue is
showing up here.
Thanks a lot for your help,
