--- Comment #2 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
Interestingly, this issue is intermittent, i.e. didn't fail for two nightly
builds. Does the code generated vary if e.g. -flto=jobserver is given and
various number of tasks might be avaiable for the build ?

Meanwhile, the error message has slightly improved, not a segfault but:
