Topic: How to use --bug-report=rr

When trying out any example from the README of https://github.com/ksil/LFPSQP.jl I am getting segfaults. Thus, I wanted to record the segfault with --debug-report==rr but the debug process itself reports an error:

julia> using LFPSQP
[ Info: Precompiling LFPSQP [213b899a-c0a5-4fcf-934b-81c0c35eb21a]

julia> x, obj_values, λ_kkt, term_info = optimize(f, x0)

I have had that happen too, but then I managed to record with rr directly (rr record julia ...). Does that work?
