[Vm-dev] Building OSVM in Windows 11 and Cygwin64 ...

[Jakob Reschke]

That's why (quoted from the doc page):

Unlike _alloca, which doesn't require or permit a call to free to free the
memory so allocated, _malloca requires the use of _freea
<https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/freea?view=msvc-170>
to
free memory.
