Comment 1 for bug 1951126

Tests:

#1 rebuild of tgt against the new glusterfs
Still failing:
$ sudo /usr/sbin/tgtd -f
tgtd: iser_ib_init(3431) Failed to initialize RDMA; load kernel modules?
tgtd: work_timer_start(146) use timer_fd based scheduler
src/tcmalloc.cc:333] Attempt to free invalid pointer 0x55f3f061eac0
Aborted

#2 Rebuild of glusterfs with tcmalloc disabled on x86

This makes it work again.
