Is the modified testcase working for you?
I'm getting segmentation fault:
(gdb) bt
#0 __GI__IO_fputs (str=str@entry=0x7fffffffa980 "keepcaps 0 TWARN :
tst_brk_: Invalid Type: 0. Using TBROK\n", fp=0x0)

#1 0x00000000004015ee in tst_print (tcid=0x4029ba "keepcaps",

#5 0x000000000040124f in main (argc=2, argv=0x7fffffffe528) at
check_keepcaps.c:113
and when I fix the crash (T_out is uninitialized) I get:
# ./check_keepcaps 1
keepcaps 0 TWARN : tst_brk_: Invalid Type: 0. Using TBROK
keepcaps 1 TBROK : check_keepcaps.c:88: dropped privs as expected
from lib/tst_res.c:
/*
* Only FAIL, BROK, CONF, and RETR are supported by tst_brk().
*/
