[Coco] C compiler crashes VCC with Nitros9

[Walter ZAMBOTTI]

Microware CC1 (Level 1) (from http://www.nitros9.org/latest/cc.dsk)
VCC 1.4.2
Nitros9 3.2.8 (Nitros9.vhd from http://www.nitros9.org/nitros9project.zip)
(Not sure why the hard disk is not 3.2.9)

I inserted Nitros9.vhd to HD0 & CC.dsk to /d0

Boots (DOS255) ok and then I copied the CC disk to the hard drive:
/d0/cmds/* to /dd/cmds
/d0/defs/* to /dd/defs
/d0/lib/* to /dd/lib
/d0/sources/* to /dd/sources
/d0/sources/sys/* to /dd/sources/sys

Then I tried compiling one of the provided samples:

chd /dd/sources
cc1 line.c
(VCC instantly crashes)

Any ideas?
