glib-2.20.5 b0rks if compiled with plain -O3
Just one more post for the category Improving Free Software: I’ve run into troubles on my laptop when yesterday I upgraded glib, which caused an infinite loop on a dependent software.
Thanks to a suggestion from Gilles Dartiguelongue, I found that the latest glib fails if compiled with a plain -O3 optimization: the problem was solved by disabling the “ipa-cp-clone” optimization (-fno-ipa-cp-clone).
All the details can be found here.
