Please attach the output of "emerge --info dev-libs/glib dev-libs/libsigc++"

Do you remember if you built glib and libsigc++ using clang or gcc?

Also, please check if using -O2 instead of -O3 allows tests to pass.

Comment 5 Fabio Scaccabarozzi 2015-06-10 20:09:26 UTC

Tests still fail with -O2 instead of -O3.

Sorry for the multiple comments, there were many requests and each time I went back checking the others :)
I remember glib was one of the next on my bug submissions, so probably it's still failing tests as well, I will submit a new bug soon if that is the case.
