I found this error on the latest version 0.24.11. Julia will freeze, Ctrl+C nor Ctrl+D will interrupt the execution or closing Julia itself.

The only solution is to close the terminal or process where julia was running.

Good luck!

Not a crash, but an infinite loop.

Hi!
I'm also running into the issue that rand(truncated(Normal(0.0, 0.0); lower = 0.0)) doesn't work.
Any chance that this could be fixed?

I use rand.(truncated.(Normal.(array_of_µ, array_of_SD); lower = 0.0)) to perform bootstrapping with many parameters and some of them just happen to be 0.0 +/- 0.0 and it would be very nice to not have to bypass each of them manually.
