[bug-gawk] Coprocessing deadlocks?

[Panos Papadopoulos]

Hi Arnold!

Happy new year!

I'm sure that you're aware of this topic in comp.lang.awk:

https://groups.google.com/forum/#!topic/comp.lang.awk/pz4gmSw0uas

If you're not, here is a simple script that seems to be malfunctioning:

BEGIN { 
cmd = "tr a-z A-Z"
print "abc" |& cmd 
cmd |& getline
print
} 

The above must print ABC, but seems to freeze (gawk version 4.2).

If you change cmd to "cat" works fine.

Regards,

Panos
