egcs internal error on inline function static data

[Luke Diamand]

Summary:

egcs 1.12 (C++) on arm/aout gives a warning about inline function static
data (which is fair enough I suppose, I haven't actually checked the
standard yet) but it then crashes with an internal compiler error.

Source file causing the error:
foo.cc
======
extern void baz();
extern void bar();

inline void myfunc()
{
    static int entered = 0;
    if ( !entered )
    {
        entered = 1;
        baz();
    }
    bar();
}

void bazbar()
{
    myfunc();
}

It works fine with 'C' rather than 'C++', or with C++ on linux glibc
x86.
