Re: Builtin echo interrupted by WINCH

[Egmont Koblinger]

Hi,

Indeed, you're absolutely right. Reminder to myself: always test
latest devel version before reporting bugs :)

I've compiled devel with "make DEBUG= MALLOC_DEBUG=" and I could not
reproduce the issue with either of the commands.

Thanks a lot! :)
