Reproducer

I have a simple program using pthreads which runs fine with the default uli=
mit
-s setting (8192) but crashes midway through execution when ran under ulimi=
t -s
unlimited:

# ulimit -s unlimited
# ./thread_stack=20
MAIN 0x7ffe292afc2c
THREAD 0x14ae0f69befc
START 6
DONE 0x14ae0f5f92a0
START 5
DONE 0x14ae0f556650
START 4
DONE 0x14ae0f4b3a00
Segmentation fault (core dumped)

Is this a glibc bug?
