yes, fails the same way

$ mzscheme -qr /usr/lib64/plt/collects/tests/mzscheme/mzq.ss
[snip]
Performed 65881 expression tests (59416 good expressions, 6465 bad expressions)
and 13996 exception field tests.

Passed all tests.

$ drschemecgc
Segmentation fault

BTW I did:
configure ...
make
make cgc
make install
make install-cgc

and it built cgc variants, but it seems it did not install the normal 3m
variants fully, cause now I get:

$ drscheme
/usr/bin/drscheme: line 68: /usr/bin/mred: No such file or directory
/usr/bin/drscheme: line 68: exec: /usr/bin/mred: cannot execute: No such file
or directory

of course it is possible this is an indication of additional parallel make
failures. I was hoping to discuss those later though.
