--- Comment #5 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> ---
As expected, r223346 went as far as r222550 and ran into the same bug which is
PR/65979.
I am now building r225710, however with -O2 and not -O1 unlike what's currently
set in the Debian package source for sh4. I expect it to run into PR/66358.
Currently, my suspicion is that this particular bug is actually PR/66358 but it
just shows differently with -O1 by miscompiling the code instead of resulting
into an ICE. If my theory is correct, we should see an ICE instead of
gengtype.c being miscompiled.
