--- Comment #53 from Óscar Fuentes <gcc_bugzilla at axeitado dot com> --- (In reply to Christoph Reiter from comment #52) > Turns out this might be fallout from the last grep update, see > https://github.com/msys2/MINGW-packages/issues/9771#issuecomment-945007372 > Needs investigating.. "this" means the problem with C++ exceptions, which indeed is fixed by building gcc after reverting to grep 3.0. The build failure with Ada, which predated the grep upgrade, persists. Eric: I'm sorry for the time you wasted on this wild goose chase.
