[Gluster-devel] NULL frame->conn cause a crash

[Emmanuel Dreyfus]

Let us forget my previous batch of crashes that were with 3.2.1. This
one iw with today's code from git:

Program terminated with signal 11, Segmentation fault.
#0  0xba0c41f8 in server_inodelk_cbk (frame=0xbad01660, cookie=0xbaf0708c, 
    this=0xba816000, op_ret=0, op_errno=0) at server3_1-fops.c:251
251                             gf_add_locker (conn->ltable, state->volume,

And indeed conn leads to a SIGSEGV as it is NUL.
(gdb) print *((server_state_t *)frame->root->state)
$7 = {conn = 0x0, xprt = 0x0, itable = 0xbb96f080, 
  resume_fn = 0xba0c42d4 <server_inodelk_resume>, loc = {
    path = 0xb98fa330 "/netbsd/usr/src/common/dist/zlib/contrib/dotzlib/CVS/Root.02151a", name = 0xb98fa365 "Root.02151a", inode = 0x0, parent = 0x0, 
    gfid = '\0' <repeats 15 times>, pargfid = '\0' <repeats 15 times>, 
    ino = 0}, loc2 = {path = 0x0, name = 0x0, inode = 0x0, parent = 0x0, 
    gfid = '\0' <repeats 15 times>, pargfid = '\0' <repeats 15 times>, 
    ino = 0}, resolve = {type = RESOLVE_EXACT, fd_no = 18446744073709551615, 
    ino = 0, gen = 0, par = 0, gfid = "rð\033òX\207Kí¨§\2304ÆWý_", 


I saved the core if someone wants more details
