Problems using libstdc++ on LinuxPPC 2000

[Paul Marquis <marquis at clearway dot com>]

Hi all,

I've built libstdc++ (2.90.8 and the latest CVS snapshot) on LinuxPPC
2000 with gcc 2.95.2 and the simple hello world program seg faults at
start up:

#include <iostream>

int main(int argc, char **argv)
{
   cout << "hello world" << endl;
}

The program crashes in the static initialization of a filebuf
(__cfile_init).  Here is a stack trace:

#0  chunk_free (ar_ptr=0x7f454c46, p=0x100ef80c) at malloc.c:3051

Here are the options I used when building gcc/libstdc++:

--prefix=/usr/local/gcc
--enable-long_long
--enable-threads=posix
--disable-namespaces
--enable-languages=c++

Could this simply be a configuration issue?  Any pointers?

FYI, this program works on Linux x86 (RedHat 6.0 and RedHat 6.1) with
the gcc/libstdc++ built with the same configuration options.
