acl_getenv() always returns NULL, hence the undefined behaviour was never triggered. This looks like a debugging leftover, though assert() would have been the safe alternative to dereferencing a NULL pointer. Signed-off-by: Peter Colberg <peter.colberg@intel.com>
_putenv_s() is recommended over _putenv() as a more secure variant, though the exact benefits are not detailed. Unlike the unsafe putenv() on Linux, _putenv() on Windows does appear to copy its argument. Use _putenv_s() anyway since it provides the same interface as setenv(). Signed-off-by: Peter Colberg <peter.colberg@intel.com>
The buffer passed to putenv() becomes part of the environment. It is the caller's responsibility to keep the buffer alive as long as the environment variable is not modified by a subsequent invocation. Signed-off-by: Peter Colberg <peter.colberg@intel.com>

This resolves the final issue before enabling address sanitizer 🥳
putenv()
should be replaced withacl_test_setenv()
andacl_test_unsetenv()
in a subsequent pull request, but for now this is sufficient to pass address sanitizer.
