(i386-linux x sh-elf) -fssa segfault

[Toshiyasu Morita]

version: CVS
   host: i386-linux
 target: sh-elf

When compiling files in the stress-1.14 testsuite at:

ftp://shell14.ba.best.com/pub.t/tm2/stress-1.14.tar.gz

using the options: 

-O2 -m4-single-only -ml -fssa -S -g

the following error occurs:

...
/blitstd.i
xgcc: Internal compiler error: program cc1 got fatal signal 11
...

The problem appears to be in flow; here is the stack backtrace:

Program received signal SIGSEGV, Segmentation fault.
