<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 1 memory leak for
llvm-project/openmp/runtime/test/tasking/omp_task_depend_resize_hashmap.c :
Direct leak of 1048576 byte(s) in 1 object(s) allocated from:
