>Description:

Not sure what caused this, but atf-run hangs in -current (jemalloc issue?)

Output stops at first test case:

tps-count: 1
tp-start: 1554120753.991543, t_cat, 3
tc-start: 1554120753.992104, align

and no further output.

Attaching gdb to atf-run indicate some deadlock in ld.elf_so:

[Switching to LWP 1 of process 535]
0xbbedecd4 in ___lwp_park60 () from /usr/libexec/ld.elf_so
(gdb) bt
#0  0xbbedecd4 in ___lwp_park60 () from /usr/libexec/ld.elf_so
#1  0xbbed22d0 in _rtld_exclusive_enter (mask=mask@entry=0xbfffd248) at /work/src/libexec/ld.elf_so/rtld.c:1725

(and no further gdb activity here either)

>How-To-Repeat:

cd /usr/tests/bin/cat && atf-run t_cat

>Fix:
n/a
