--- Comment #31 from Steffen Hau <steffen at hauihau dot de> ---
Just a short update.
With LTO enabled, configure thinks I have a buggy GCC:
checking if gcc has a visibility bug with class-level attributes (GCC bug
26905)... yes
configure: WARNING: Your gcc is not -fvisibility=hidden safe. Disabling
visibility
I've then added -ffat-lto-objects to my ${C,CXX,Ld}FLAGS and the warning
disappeared.
The build failes at the same place, but instead of a segmentation fault I now
get a illegal instruction error:
/bin/sh: line 1: 10795 Illegal instruction SAL_USE_VCLPLUGIN=svp
