I missed to MFS the fix to releng.12.1, which was branched at r352480. What happened is that overflowing the sackblks[] changed sackhint.nexthole = to an invalid value which was not NULL. From the core provided: sackblks =3D {{ start =3D 0xc1f54a52,=20 end =3D 0xc1f54ffe }, { start =3D 0xc1f5229e,=20 end =3D 0xc1f5284a }, { start =3D 0xc1f5229e,=20 end =3D 0xc1f5284a }, { start =3D 0xc1f5229e,=20 end =3D 0xc1f5284a }, { start =3D 0xc1f5229e,=20 end =3D 0xc1f5284a }, { start =3D 0xc1f51746,=20 end =3D 0xc1f51cf2 }},=20 sackhint =3D { nexthole =3D 0xc1f5119ac1f50bee,=20 sack_bytes_rexmit =3D 0x0,=20 last_sack_ack =3D 0x3fe9f863,=20 ispare =3D 0x0,=20 sacked_bytes =3D 0xb65,=20 _pad1 =3D {0x0},=20 _pad =3D {0x0} }, Since I can't get any changes in BETA2 anymore, the fix will be in BETA3 or RC1. --=20 You are receiving this mail because: You are the assignee for the bug.=
