async signals, which I can't do with current
tools.

code does, which i was porting into go)

hi,
Maybe I wasn't clear, I am indeed using os.signal package. But it doesn't do
what I want! I want to trigger a panic in main function , seems there is no
way to do it by using a signal channel .
Thanks

Hi Ian,
Sorry for replying late.
1: operating system is linux
2. golang 1.7
3. I'm statically linking Go with C++ code, so I guess that is
-buildmode=c-archive.
Thanks

Hi,
I've successfully compile and staticlly linked my C++ project and CGO , I
was trying to get on demand CPU profling to work, but it keeps generating
empty outputs.
The CPU profiling page mentioned that if code built in C mode, i need to do
something with SIGPROF , but no examples were given
