Re: [Discuss-gnuradio] symbol already exists: cannot reuse! runtime error

Hi Eugene,

ouch, that's a heavy bug, considering we have blocks called agc2 in-tree.

Thanks for reporting this! Do you want to create an issue on
https://github.com/gnuradio/gnuradio/issues , or would you prefer we do
that? (I'd of course personally prefer you'd, as the discoverer &
solver, at least get the authorship of that ticket)

Best regards,

Marcus
