Subject: radix tree test suite: fix incorrect allocation size for pthreads
From: Colin Ian King <colin.i.king@xxxxxxxxx>
commit cac7ea57a06016e4914848b707477fb07ee4ae1c upstream.
Currently the pthread allocation for each array item is based on the size
of a pthread_t pointer and should be the size of the pthread_t structure,
so the allocation is under-allocating the correct size. Fix this by using
the size of each element in the pthreads array.
Static analysis cppcheck reported:
tools/testing/radix-tree/regression1.c:180:2: warning: Size of pointer
'threads' used instead of size of its data. [pointerSize]
