Bug#824207: ghostscript: Segmentation fault when printing in color mode

[Andreas Messer <andi@bastelmap.de>]

Package: ghostscript
Version: 9.06~dfsg-2+deb8u1
Severity: normal

Dear Maintainer,

when trying to make a print using colors from any application (gimp, inkscape...)
no printing happens. Ghostscript segfaults due to mutex issue in glibc. The 
problem is related to an already fixed bug in ghostscript's recursive mutex 
handling:

http://bugs.ghostscript.com/show_bug.cgi?id=695862

The problem only occurs on Intel Skylake based machines supporting TSX memory like 
XEON cpus. (Supporting hardware accelerated mutexes) These mutexes are sensitive 
to wrong usage, e.g. double unlocking which actually happens in ghostscript due 
to the buggy implementation

Here is a backtrace:

Updating to ghostscript package from stretch fixes the issue for me.
