<pre>I compiled OpenMP runtime and tests with AddressSanitizer:
-DCMAKE_CXX_FLAGS:STRING=-fsanitize=address
-DCMAKE_C_FLAGS:STRING=-fsanitize=address
-DOPENMP_TEST_FLAGS:STRING="-g -DDEBUG -fsanitize=address"
AddressSanitizer reports a memory leak when running
openmp/runtime/test/tasking/hidden_helper_task/capacity_nthreads.cpp :
