ports/73914: /usr/ports/lang/scm marked broken unjustifiedly due to Segmentation Fault

[dai]

Thanks for reply.

I first posted to

http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/71684

to point out the location of the problem with no followups and I
sent-pr to ports/73914.

env: something like "No match for the query pattern" in Japanese.

The compilation finishes successfully with "-O0" but there are some
loss in significant digits, which is told by "./scm -l r4rstest."

% make "CFLAGS=-O3 -DGCC_SPARC_BUG"

or

% make CC=gcc34 CFLAGS=-O3

is needed to have scm working with my actual system.
