source: tests/malloc.cfa@ 7aa246cb

Last change on this file since 7aa246cb was 10b5970, checked in by Michael Brooks <mlbrooks@…>, 10 months ago

Fix many test-suite- and libcfa-caused unused variable warnings.

In scope are easy fixes among tests whose sole warnings were unused variable. Reduces the wflags lax list by 40%.
