--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Technically, this patch only adds '{ dg-do run }' which has the effect that the
code is not only run once but multiple times with different compiler options
(-O1, -O2 etc.).
Your code fails to execute with -O0 and a timeout of 300 (seconds, I guess,
which is then 5min). – I think your system does not do any offloading to a GPU.
Hence, it would be a host-only run.
It runs here with -O0 in 0.620s and compiles in 2.194s (cold run, re-run:
1.062s). And that's while bootstapping GCC in parallel on this laptop.
As you could nail it down to a single commit, I assume, you could reproduce the
problem – still, I am completely lost why it fails for you at -O0. Can you try
to debug it a bit more?
