>Description:
When compiled with FreeBSD defaults (gcc-3.4.2), scmlit and scm crash
with "Segmentation Fault" in eval.c at the line 2090 with core dump:

eval.c: 2090 x = arg1;

If I trace the program with gdb and dumped core files, the variable
arg1 in the function "static SCM ceval_1(x)" disappears except when
compiled with the optimization option "-O0 (gcc default)."

This seems to be a gcc-3.4.2 bug because the program scompile and
work expectedly when compiled with gcc-3.4.3 from the port.
    
>How-To-Repeat:
/usr/ports/lang/scm% make     
>Fix:

	Use gcc-3.4.3 or later from the port or compile with
	"-DGCC_SPARC_BUG" if with gcc-3.4.2.
