GNU Radio

The previous problem disappeared when I changed library to boost 1.37.

Thanks!

I have seen this issue before. I would like to replicate it on my own
machine if possible.

Was this a custom boost build?
What operating system and version?

Thanks

FWIW, I have compiled the uhd with boost 1.42 on windows. :slight_smile:
