--- Comment #11 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- (In reply to Markus Trippelsdorf from comment #10) > But this isn't tcmalloc, but jemalloc: > > https://github.com/jemalloc/jemalloc/blob/dev/test/integration/mallocx.c#L70 Just to clarify. jemalloc is a pure C application, so its assertion failure is unrelated to this bug.
