Marek Polacek <mpolacek at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mpolacek at gcc dot gnu.org --- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> --- Note that the package explicitly uses -ftemplate-depth=25 (without that the .ii files compiles fine). So maybe just some changes in libstdc++ that trigger the limit?
