[ltt-dev] Crash in lttv-0.12.12

[Gregory Haskins]

Hi Mathieu, ltt-devs,

Found this on lttv-0.12.12 against 30-rc5-0.136 trace data when I try to
open the RV.

Program received signal SIGSEGV, Segmentation fault.

I uploaded the trace and coredump here:

ftp://ftp.novell.com/dev/ghaskins/lttv-0.12.12-crash.tar.bz2

and the binary I used can be found here:

http://download.opensuse.org/repositories/home://ghaskins://lttng/openSUSE_11.1/x86_64/lttv-0.12.12-3.1.x86_64.rpm

Note that this seems specific to this particular trace.  RV opens fine
for most other traces I try.

Let me know if there is anything I can do to help or provide more info.

-Greg
