warnings while using nprof

This might be due to an out-of-date nprof that you have in this repo?

in no particular order from a generated v8.log file being processed.
Yes, or too new. With what version of node and node-profiler are you seeing this?
0.6.19, might also cause not to show a call profile.
profiler version 1.1.0
I think it's a matter of nprof being too new, not much has changed upstream. Still, can you try the update-nprof branch?
with that branch I get:
line 4147: unknown code state: 0x2e170abe27f0

Maybe the V8 people simply forgot to upgrade the profiler tools... can you try the downgrade-nprof branch? If that doesn't fix it, I'll have to patch V8.
I tried, but I'm back to the scenario of version 1.1.0 (the version of profiler in npm)... in both branches I get no call profile, which is actually the most useful for me potentially!
Okay, noted. Can you upload the v8.log somewhere?
plz check your skype for a link to a gist ;)
meh, whatever: https://gist.github.com/3048132b7d714e6a5071
Okay, this should be fixed per df1fc75.
You may still get a warning or two - there's a function called <ul id="files">.files.map.icon /foo/bar/baz (probably some string/function mapping). The V8 in 0.6 doesn't escape the function name properly but that's fixed in v0.8.
