problem with 'make test' with bigloo 4.0b

It makes it to process.scm ok, but then prints:

process.scm:
*** ERROR:write/display:
Broken pipe -- #<output_port:stdout>
*** ERROR:write/display:
Broken pipe -- #<output_port:stdout>
*** ERROR:write/display:
Broken pipe -- #<output_port:stdout>

until I kill it from another terminal.

I have configured with:

VERSION=4.0b-1
TARGET=${ROOTDIR}/${VERSION}
./configure --prefix=${TARGET} --finalization=yes 
--lispdir=${TARGET}/lispdir --bee=full
