           Summary: segmentation fault
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: dave at boost-consulting dot com
                CC: gcc-bugs at gcc dot gnu dot org

G++ first reports an internal compiler error and segfault and then appears to 
go into an infinite loop when I try to compile the enclosed under Cygwin

I cannot reproduce this problem on i686-pc-linux-gnu with 3.4 (20031107), 3.2.3, or 3.3.1 
(20030707), 3.3.3 (20031105), or 3.3 (20021216). Can you provide the exact comand you invoke 
to get the seg fault? Also provide the exact version of gcc, by giving the output of gcc -v?

What happens if you remove the "-g" from the command line?

3.3.1 is getting old at this point and your compiler is not a FSF compiler, can you test 
3.3.2 and maybe also report this to cygwin?

I can't reproduce this with either 3.3.1 or 3.3 branch (20031122) cross-compilers to i686-pc-
cygwin.

The stack size on cygwin is too low, you have to compile GCC with a raised stack size 
(look at man ld or info ld for the option to pass to gcc to recompile gcc).

Is it not possible to print a better error message than 'segmentation error' in this case?  For 
example, on Darwin GCC prints:

Out of stack space.
Try running `ulimit -S -s unlimited' in the shell to raise its limit.

(See config/rs6000/host-darwin.c.)

Yes it is but this is a known issue with cygwin and that you cannot change the stack size by using 
limit/ulimit on cygwin at all so you have to recompile GCC anyway.
