Internal compiler error in g++ on Alpha

[Falk Hueffner <falk dot hueffner at student dot uni-tuebingen dot de>]

Hi,

I found this while trying to compile ddd 3.1.90. Here's a simplified
test case:

/*
  % uname -a
  Linux borkum 2.2.13 #2 Wed Oct 20 16:30:02 CEST 1999 alpha unknown

  % c++ -v       
  Reading specs from /usr/lib/gcc-lib/alpha-linux/2.95.2/specs
  gcc version 2.95.2 19991109 (Debian GNU/Linux)

  % c++ -c HelpCB.C # works ok
  % c++ -O1 -c HelpCB.C
  HelpCB.C: In function `void PopupTip()':
  HelpCB.C:21: Internal compiler error.
  HelpCB.C:21: Please submit a full bug report.

  % c++ -O2 -c HelpCB.C

class MString {
    char *_mstring;
public:
    ~MString() {
	delete _mstring;
    }
};

void PopupTip()
{
    MString tip;

    for (int run = 0; run < 18; run++) {
	bool ok = false;

	if (!ok && run <= 8)
	    continue;

	return;
    }
