Subject: v6 crash bugreport [Re: [patch v6 00/21] record-btrace: reverse]
Date: Thu, 26 Sep 2013 19:16:00 -0000 [thread overview]
Message-ID: <20130926191611.GA13376@host2.jankratochvil.net> (raw)
In-Reply-To: <1379676639-31802-1-git-send-email-markus.t.metzger@intel.com>
Hi Markus,
./gdb ./gdb -ex start -ex 'record btrace' -ex stepi -ex 'record instruction-history 0'
Segmentation fault
Program received signal SIGSEGV, Segmentation fault.
0x000000000089dd86 in btrace_find_insn_by_number (it=0x7fffffffd4c0, btinfo=0x291fc98, number=0) at btrace.c:1243
1243 end = bfun->insn_offset + VEC_length (btrace_insn_s, bfun->insn);
(gdb) p bfun
$1 = (const struct btrace_function *) 0x0
(I am aware I was asking to reduce the number of NULL checks there.)
Thanks,
Jan
