I traced the "infinite loop" to tokenizer.c:tok_get around line 1368:
while (Py_ISALNUM(c) || c == '_') {
c = tok_nextc(tok);
}
Adding a `printf` statement at the beginning of the loop:
printf("tok_get: third while: c = %c (%d) ... Py_ISALNUM=%d\n", c,
c, Py_ISALNUM(c));
Output:
tok_get: third while: c = � (-1) ... Py_ISALNUM=2
tok_get: third while: c = � (-1) ... Py_ISALNUM=2
tok_get: third while: c = � (-1) ... Py_ISALNUM=2
tok_get: third while: c = � (-1) ... Py_ISALNUM=2
tok_get: third while: c = � (-1) ... Py_ISALNUM=2
tok_get: third while: c = � (-1) ... Py_ISALNUM=2
tok_get: third while: c = � (-1) ... Py_ISALNUM=2
tok_get: third while: c = � (-1) ... Py_ISALNUM=2

I may not spend much time on this bug, unless someone can hint at what might
have gone wrong here?
As for 2.6-maint, I will find that out sometime this week.
