That should be "glibc malloc"; and only old versions. The bug
is fixed in glibc 2.28, at least; likely earlier. (glibc takes
forever to build) It's present in 2.24-11+deb9 on Debian.
MALLOC_ARENA_MAX=1 MALLOC_ARENA_TEST=1 does not seem to help.
I forgot one other parameter which IS the culprit in older glibc versions:
MALLOC_MMAP_THRESHOLD_=131072 # or whatever fixed value you want
So the sliding mmap threshold was the problem in glibc; but it's
fixed upstream, at least. Just have to wait for distros to roll
it out...
