[Valgrind-developers] Valgrind on PPC

I was trying out valgrind on powerpc recently and while it works fine with
C applications, C++ apps seem to be giving it some serious problems. I
compiled helloworld.cpp, basically just 'cout << "Hello world." << endl;',
and when I run it through valgrind I get this assertion failure:
==20360== Reading syms from /lib/libc-2.2.5.so
==20360== Reading syms from /lib/libm-2.2.5.so
==20360== Reading syms from /usr/lib/libstdc++-3-libc6.2-2-2.10.0.so
valgrind: vg_symtab2.c:272 (addScopeRange): Assertion `range->size > 0'
failed.

Enabling debug, I see this:

}
47307 type=224 othr=0 desc=0 value=0x8C strx=0
So the failure is at the outer most scope. The assert fails because
range->size = -0xe0. I'm not sure if it's a coincidence that
0x16c=0x8c+0xe0. Any ideas what could be going wrong here? I have tried
several C++ programs and they all trigger this, while I haven't found a
single C program that fails so far. GCC version is 2.95.4.
