Where does it come from? That's a good question - I understand that sprinkling NULL checks for supposedly-non-NULL values can mask unrelated problems. Two more observatio= ns as they just happened a minute ago: 1) the real bug seems to be related to #29605 2) even with this patch I still see segfaults in strlen() at that call site (though not right away), so maybe it's not a NULL value at all. --=20 You are receiving this mail because: You are on the CC list for the bug.=
