MacOS tools can only be built natively on MacOS due to MacOS's
licensing. I.e. we won't ever be able to do so using cross-compilers.

If the bug was in GCC it would apply to all host OS and not be limited
to the MinGW toolchains. 

However, even if GCC should leak (which is very likely), this should be
of marginal importance, because GCC apps are "one-shot apps", after
running which the OS is supposed to clean up. If they cause permanent
memory leakage, it would mean the runtime system underneath has a
resource management issue and/or doesn't meet GCC's expectations.
