Bug#521737: Root cause of SEGV is known for quite some time, still suspected bug



Hi all,

I just found the following on the net:

http://www.alphalinux.org/archives/axp-list/March2001/0337.shtml

It seems that the possible SEGV in memchr is well known if an overestimated
third argument (the maximum length to be scanned) is passed in. Therefore I'd
say that the bug is acutually in a subroutine of strstr that passes a too large
value to memchr (I think it was str_two_way_short_needle), which is unportable
code.

Best,
Michael
