[ruby-core:93522] [Ruby master Bug#11467] Memory leak in win32 signal init

Issue #11467 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Feedback

`Init_signal` is only called once at startup.  It appears the memory allocation here happens inside `signal`, in the MS C runtime.  Does Windows provide a way to free such memory?
