Patrick Palka <ppalka at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- See Also| |https://gcc.gnu.org/bugzill | |a/show_bug.cgi?id=105322 --- Comment #4 from Patrick Palka <ppalka at gcc dot gnu.org> --- Oops, I was only going to suggest removing the optimization pragmas either manually or by compiling with -O etc. I suspect the subsequent trees_out::insert ICE is a manifestation of PR105322.. it's not seen in release builds because it's caused by a failing assert that get compiled away in release builds.
