Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |RESOLVED Resolution|--- |INVALID --- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- So there's no exception then. This is why you were asked to read https://gcc.gnu.org/bugs/ before filing a bug, and explain exactly what you're doing and what you're seeing. _GLIBCXX_PARALLEL is not supposed to enable those assertions, but apparently I didn't fix Bug 71856 completely, I'll reopen it.
