This is something we're interested in doing, eventually. We would need to coax Node to generate debug output in some form that allows us to map JITted code back to...
The exception is coming from libelfin as it tries to figure out what type the attribute tagged as DW_AT_sec_offset is. I think the attribute type is in the user-defined range,...
Backing out a previous change (#96, removed by #128) appears to fix this issue. The code relied on exceptions while walking through compilation units in an effort to improve performance....
Which version of libelfin are you running? If coz did not crash and you just get an empty profile then this could be a different issue (maybe #109).
I am actively looking into this issue, but I haven't made any headway yet. I'll try to keep you updated.
I can't reproduce this on my machine (Ubuntu 17.04) using the apt-installed coz. I'll give it a shot on a Debian machine soon.
You may be right about coz missing thread creation, but the one other possibility is that openalpr is `fork`ing a new process. Could you verify that `alpr` is running in...
I'm not sure there's a good way to fix this issue at the moment. My attempts to initialize the profiler in the replaced `__libc_start_main` lead to segfaults (probably because static...
Implementing #60 should fix this issue, although this feature is in very early stages.
I'm not excited about paying `ptrace`'s ~8% overhead all the time, since this would distort the program runtime quite a bit more than Coz already does. Extra instrumentation isn't ideal...
