Log of my second encounter of this behaviour

Description abmelden22 2014-04-09 20:17:08 UTC 
I am using Arch Linux x86_64. After the last update of the fontconfig, I wanted to flush the font cache:

what does it say if you run fc-cache with FC_DEBUG=128?

Comment 5 abmelden22 2014-06-13 21:23:22 UTC 
The bug seems to have re-appeared in version 2.11.1 (see new attachment).
Comment 6 abmelden22 2014-06-13 21:24:21 UTC 
I was testing fc-cache on a 32-bit system this time, in case that matters.

The above fix isn't yet in any released one. please try again with git's or backport a patch.
Comment 8 fanf42 2015-07-30 11:46:49 UTC 
It seems that the bug can be workarounded with:

1/ fc-cache -vrf
=> clean cache (and then fail on regeneration) and then then:
2/ fc-cache -vf" 
=> no --really-force the second time, so the parameter is correct in scanDirs that time. 

Hope it helps other.
