More infos :

A better stack dump of the same SIGSEGV (no -O2 switch) :

#0  0x8067d4b in fragaddrmatch (i=0x8113a88, j=0x8311b78) at spp_defrag.c:628
#1  0x80685e1 in PreprocDefrag (p=0xbffff598) at spp_defrag.c:945
#2  0x805a1ae in Preprocess (p=0xbffff598) at rules.c:3427
#3  0x804b776 in ProcessPacket (user=0x0, pkthdr=0xbffffa5c, pkt=0x80daae2 "") at snort.c:512
#4  0x4001b6dd in pcap_read () from /usr/lib/libpcap.so.0
#5  0x4001bd3f in pcap_loop () from /usr/lib/libpcap.so.0
#6  0x804cfbe in InterfaceThread (arg=0x0) at snort.c:1441
#7  0x804b617 in main (argc=7, argv=0xbffffbe4) at snort.c:445

And, alas, another SIGSEGV stack dump :

#0  0x40194a4c in free () from /lib/libc.so.6
#1  0x401949fd in free () from /lib/libc.so.6

#4  0x804b776 in ProcessPacket (user=0x0, pkthdr=0xbffffa5c, pkt=0x80daae2 "") at snort.c:512
#5  0x4001b6dd in pcap_read () from /usr/lib/libpcap.so.0

#8  0x804b617 in main (argc=7, argv=0xbffffbe4) at snort.c:445
