Steps to reliably reproduce (on Win10):

load vm_deal.mat  # attached
nlay = 20000
tmp = repmat ({'Line'}, 1, nlay);
[bshp(1:nlay).Geometry] = deal (tmp{:})

nlay = 16000 still goes fine on my box.
nlay = 17000 leads to a silent crash.

After  '__vm_enable__ (0)'  there's no crash.

Has been working fine for years on Matlab and Octave.
Don't know if it's a regression as it only crashes using the bytecode
interpreter :-)
