--- Comment #32 from jackdachef@gmail.com --- the issue is quite complex and another aspect is that the box on which wine was compiled plays an important role, let me elaborate:
due to a hardware upgrade I'm on a Haswell-based Xeon (E3-1245V3), previously Lynnfield Core i7 860 - both with latest microcode updates
every attempt to compile wine gcc 4.7.4, 4.8.3, 4.9.0 hardened/non-hardened toolchain (~amd64 Gentoo)
"tame" CFLAGS/CXXFLAGS: -O2 (or additional optimizations)
32bit or 64 bit version led to PDF-XChange Viewer crashing during saving of the annotated changes
whereas with an older (luckily) archived version of the compiled wine binary with the Core i7 860 (1.7.16, but a newer version up to afaik 1.7.18 also worked - unfortunately didn't backup that one)
*every single time* it (most preferrably the 32 bit version) works
this is yet another factor to take into consideration :(
