--- Comment #31 from Martin Liška <marxin at gcc dot gnu.org> --- Created attachment 43781 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43781&action=edit Partially reduced test-case I've got 120KB partially reduced test-case. Any further reduction is not much possible. I'm able to reproduce that with -O1 -Woverloaded-virtual. It's super-weird issue, any ggc parameters adjustments do not make any change. I would recommend to create Debian-specific issue and somebody will need to investigate which patch is responsible for that.
