Jan Hubicka <hubicka at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |WAITING --- Comment #20 from Jan Hubicka <hubicka at gcc dot gnu.org> --- I re-tried with g:0ad6a2e2f0c667f9916cfcdb81f41f6055f1d0b3 and it builds all fine even with --param ggc-min-expand=0 --param ggc-min-heapsize=0. It seems that --enable-checking=gcac is now noop. @doko: perhaps using --param ggc-min-expand=0 --param ggc-min-heapsize=0 on your setup may trigger the problem again. There is some chance that i.e. the qt headers are the cause, but I am tempted to close the bug as WORKSFORME after committing the refactoring patch.
