[M3devel] segmentation fault upon ./install-cm3-compiler.sh upgrade

[Neels Janosch Hofmeyr]

minimal binary as available on the download page.
  http://modula3.elegosoft.com/cm3/cm3-min-POSIX-LINUXLIBC6-5.4.0.tgz
  http://modula3.elegosoft.com/cm3/cm3-src-sys-5.4.0.tgz
  http://modula3.elegosoft.com/cm3/cm3-src-gnu-5.4.0.tgz
  http://modula3.elegosoft.com/cm3/cm3-src-std-5.4.0.tgz
