Log:
clang compiler warnings: Fix sometimes-initialized warning in func_math

This patch fixes a bug in a unit test in func_math where a variable could be
passed to ast_free that wasn't allocated. This patch corrects the issue and
ensures that we only attempt to free a variable if we previously allocated
it.
