The test is "testsuite/misc-ming.all/NetStream-SquareTest". (The
segfault doesn't occur every time. After all, it's a buffer overflow, so
the behavior is somewhat unpredictable.)

Yes, the line is truncated in the error message. The buffer that msgline 
points to is only 1024 bytes long. The "if(column < 1023)" already 
stores only 1023 characters in the message. The NULL should appear right 
after that.
