Hi Khaled,

Did you see the current build failures?
Here are two failures:
http://tinderbox.libreoffice.org/cgi-bin/gunzip.cgi?tree=MASTER&brief-log=1488779385.27281
http://tinderbox.libreoffice.org/cgi-bin/gunzip.cgi?tree=MASTER&brief-log=1488782916.5676
Interestingly it's the same tinderbox which is sometimes happy with the test, sometimes fails with 75 and sometimes fails with 91 as text width.
Clearly we have some wierd behavior here.

Best Regards,
Tamás
