Mesh2faust error with material density higher than 4019

[LOM-instruments]

I think I found a bug. When entering material density higher than 4019, program crashes.

mesh2faust --material 70E9 0.31 4019 --showfreqs --infile kocka.obj works fine

mesh2faust --material 70E9 0.31 4020 --showfreqs --infile kocka.obj results in Job 1, 'mesh2faust --material 70E9 0.31…' terminated by signal SIGSEGV (Address boundary error)

Running the latest version of mesh2faust 1167625 and eigen 3.4.0_1.

Thank you
