Major - P3 Our ASAN variant in the evergreen feature branch is detecting LeakSanitizer errors when running the wt3120-filesys & wt2909_checkpoint_integrity csuite tests. We get the following error:
[2021/12/23 06:36:16.411] ================================================================= [2021/12/23 06:36:16.411] ==132599==ERROR: LeakSanitizer: detected memory leaks [2021/12/23 06:36:16.411] Direct leak of 66 byte(s) in 1 object(s) allocated from: [2021/12/23 06:36:16.411] #0 0x4b02ed in strdup /data/mci/8a325c5dac104a1f376737aa7d08a24c/toolchain-builder/tmp/build-llvm.sh-9LL/llvm/projects/compiler-rt/lib/asan/asan_interceptors.cc:447:3 [2021/12/23 06:36:16.411] #1 0x4f74b5 in dstrdup /data/mci/ffb32f27289d27862cdf1a5212edf17c/wiredtiger/cmake_build/../test/utility/misc.c:452:14 [2021/12/23 06:36:16.500] SUMMARY: AddressSanitizer: 66 byte(s) leaked in 1 allocation(s).

The above error is due to the CTest invocation of wt3120-filesys & wt2909_checkpoint_integrity passing in a build directory argument (-b). This particular option allocates memory to hold the build directory path string but doesn't free the memory on exit/cleanup.
Definition of Done:
- Free the memory backing the build directory argument on testutil_cleanup.
