--- Comment #4 from Thomas Schwinge <tschwinge at gcc dot gnu.org> --- (In reply to Thomas Schwinge from comment #2) > However, in my "--enable-checking=yes,df,fold,rtl" build I'll then run into > a different ICE with the original 6.5 MiB file... :-/ So there is more work > to be done here. I'll now re-C-Reduce for that ICE, and try to find out > whether that's a known/already fixed issue or something new. That other ICE seems to be PR79732, already fixed in gcc-6-branch r246188. (I had noticed just earlier today that my GCC 6 build that I run the C-Reduce on was not exactly up-to-date. I'm now in the process of updating it.)
