I'm trying to make bootstrap with -fssa enabled, using gcc 20000315 as
the host compiler on alphaev6-unknown-linux-gnu.
It has a problem with makeinfo, which bombs on gcc.texi at
for (tindex = output_paragraph_offset - 1; tindex >= 0; --tindex)
{
c = output_paragraph[tindex]; /* <============== /*
if (c == ' '|| c == '\n')
output_paragraph[tindex] = '\n';
else
break;
}
with the following backtrace:
(xxgdb) run -I../gcc ../gcc/gcc.texi
Making info file `gcc.info' from `../gcc/gcc.texi'.
Program received signal SIGSEGV, Segmentation fault.

I'm not at all familiar with makeinfo, so I hope someone else might be
able to figure out what is going on.
