Is there any macro or function to get a local becktrace, i.e., the stack of calls porting the execution there at run-ime? Thanks for help.

`catch_backtrace()` when it’s in a catch block, otherwise there’s a function for stack traces as well which I don’t remember right now

```julia
help?> stacktrace
search: stacktrace StackTraces

  stacktrace([trace::Vector{Ptr{Cvoid}},] [c_funcs::Bool=false]) -> StackTrace

  Returns a stack trace in the form of a vector of StackFrames. (By default stacktrace doesn't return C functions, but this can be enabled.) When called
  without specifying a trace, stacktrace first calls backtrace.
