My guess would be that most segfaults are caused by the much more
aggressive optimization based on the assumption that "this" must never
be NULL in C++. 

QT5, Chromium and Kdevelop all call methods from a NULL pointer and
crash for this reason. -fno-delete-null-pointer-checks is a workaround.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68853 for an analysis
of the Chromium crash.
