 The bug is not aarch64 specific and also occurs on other architectures
 including amd64.
 
 If mmap is called with a non-zero hint (and not MAP_FIXED) and
 collides with an existing allocation, it only succeeds if
 the mapping fits into the first gap.
 
 The first gap on amd64 seems to be a bit larger so that the mapping
 used by nodejs still fits.
