node-tick-processor problem in v0.11.13

[Michael Monashev]

Hi!

After updating Node from v0.10.31 to v0.11.13 I can't effectively use
--prof flag and node-tick-processor. The output looks like this:

line 17722: unknown code state: undefined
line 17723: unknown code state: 0xf6081d8
line 17724: unknown code state: 0xf6a20b8
line 17725: unknown code state: undefined
line 17726: unknown code state: undefined
...
Statistical profiling result from v8.log, (1544 ticks, 221 unaccounted, 0 excluded).

Hi Michael! Please post your issue to https://github.com/sidorares/node-tick/issues/new

Can you try version of node-tick-processor from 0.11.x branch? v8.log does not have v8 version in the header and format is different between versions. I hope I'll add some heuristics to guess correct v8 version (or use command-line switch)

Also please read https://github.com/sidorares/node-tick/issues/10
