I've checked several tests, I see that for all tests failure occurs in
function gomp_icv (). E.g.:
icv-2:
#0 gomp_icv (write=true) at ../../../libgomp/libgomp.h:494
#1 omp_set_num_threads (n=6) at ../../../libgomp/env.c:1282
#2 0x0000000000404014 in tf ()
#3 0x000000000040d063 in start_thread ()
#4 0x0000000000450139 in clone ()
lock-3:
#0 gomp_icv (write=true) at ../../../libgomp/libgomp.h:494
#1 omp_test_nest_lock (lock=0x6dd580 <lock>) at
../../../libgomp/config/linux/lock.c:109
#2 0x0000000000403fbc in tf ()
#3 0x000000000040ccd3 in start_thread ()
#4 0x000000000044fda9 in clone ()
