another mysterious segfault

[Lars Damerow]

Hi folks,

I'm trying to track down another mysterious segfault in cfagent. It doesn't
happen every time I run cfagent, which makes it very frustrating. Here's the
backtrace:

    #0  0x00002aaaab3f04c8 in _int_malloc () from /lib64/libc.so.6
    #1  0x00002aaaab3f1d6b in malloc () from /lib64/libc.so.6
    #2  0x000000000041d99e in AppendItem (liststart=0x7fffffd8dbe8, 
itemstring=0x5ece80 "# To use this server type you should add -query host or 
-indirect host", classes=0x0)
        at item.c:316

    #11 0x00007fffffd8ff58 in ?? ()
    #12 0x0000000000000000 in ?? ()

I'm puzzled as to why it's segfaulting during a malloc while reading in that
file; the only thing of note for the particular line it's reading is that the
line appears twice in the file.

Does this sound familiar to anyone?

thanks,
lars
