Subject: fix sem_close regression test
X-Git-Url: http://nsz.repo.hu/git/?p=libc-test;a=commitdiff_plain;h=a0c28c7673121dcb9305d1ea21aa5a42a5d9929d

fix sem_close regression test

sem_close with O_CREAT takes 4 parameters, not 3. The last parameter,
the initial value for the semaphore, had an arbitrary value from
whatever was on the stack, and lead to spurious failures with EINVAL
when it happened to be greater than SEM_VALUE_MAX. Since there isn't
error checking in this test, this lead to a segfault in the first
sem_post call.
