Hi Scilab developers, 



Ever since Raspberry Pi 4 released with extra RAM of 2G and 4G version, Scilab could be run quite smoothly under Ubuntu Server RaspPi version. (In fact, the speed is quite acceptable even in Raspberry Pi 3). Even it is still having some bugs, the binary provided by the Ubuntu repository could just run after apt-get in Raspberry Pi. (Scilab 6.01 / 6.02 under current LTS 18.04 and 19.10 respectively). 



Since the release of Scilab 6.1 is quite new, it is only available in unstable release, or we need to recompile from scratch (no-gui). However, even the scilab-cli could launch with both method, I encounter the following crash whenever Scilab 6.1 (scilab-cli) start to echo character '0' on the screen

A fatal error has been detected by Scilab.

Please check your user-defined functions (or external module ones) should they appear in the stack trace.

Otherwise you can report a bug on http://bugzilla.scilab.org/ with:

* a sample code which reproduces the issue

* the result of [a, b] = getdebuginfo()

* the following information:

[ubuntu:24308] Signal: Aborted (6)

[ubuntu:24308] Signal code:  (-6)



Call stack:

   1: 0x324d8  <raise>                          (/lib/aarch64-linux-gnu/libc.so.6)

End of stack

Anyone has any idea on what likely causing the problem?
