I was compiling origin/master today with the DEVELOPER compiler flags today and was greeted by
t/helper/test-lazy-init-name-hash.c: In function ‘cmd_main’:
t/helper/test-lazy-init-name-hash.c:172:5: error: ‘nr_threads_used’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
printf("avg [size %8d] [single %f] %c [multi %f %d]\n",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
nr,
~~~
(double)avg_single/1000000000,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(avg_single < avg_multi ? '<' : '>'),
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(double)avg_multi/1000000000,

nr_threads_used);
~~~~~~~~~~~~~~~~
t/helper/test-lazy-init-name-hash.c:115:6: note: ‘nr_threads_used’ was declared here
int nr_threads_used;
^~~~~~~~~~~~~~~Fix this issue by assigning 0 to 'nr_threads_used'.

Slightly reworded the commit message. I'd really like this patch to be included such that I can compile git with the DEVELOPER_CFLAGS flags.
