interesting ... you are building LO 4.4.1.1 or older?
looking at the git log there is this apparent work-around:
http://cgit.freedesktop.org/libreoffice/core/commit/?id=8bb0446974282b32d06cdbd35af83f91e033b4af
not sure if it's the same bug... in case this is triggered by some sort
of de-virtualization new in GCC5 then i guess it is LO's fault
because the acquire() / release() was not dll-exported.
i will push that to the libreoffice-4-3 release branch to get it into 4.3.7.
(i've only tried to build current master, which works fine now with
workaround for the bug from the description)
