The flag -fcheck=recursion is enough to trigger the runtime error and I see it
with 4.9.3, but not with 4.8.5.

Ah sorry, here is the tarball with the missing file and also the correct flags.
And please remove the 'severe' from regression, I first thought this was with
default flags.

--- Comment #3 from Jürgen Reuter ---
Indeed it is the -fcheck=all flag that causes the problem. I will send a
smaller reproducer soon.

--- Comment #2 from Jürgen Reuter ---
The problem doesn't appear with our strict flags
-O0 -fbacktrace -fcheck=array-temps,bounds,do,mem,pointer
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80361
--- Comment #1 from Jürgen Reuter ---
Bug only appears when using the flags -fbacktrace -ggdb -fcheck=all.
With default flags -O2 -g it doesn't occur.
