--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> --- (In reply to p.vanh...@oma.be from comment #0) > Unfortunately this appears to be a heisenbug. I tried generating the > preprocessed file with -save-temps, but the ICE goes away when using that > file (or even when generating the file). So I can only hope you can > reproduce it with the attached file... Let me know if there is anything else > I can do. --param ggc-min-expand=0 --param ggc-min-heapsize=0 can be useful when dealing with bugs like this, BTW.
