Under groff 1.18.1.1 on Cygwin or Linux Fedora, pspic causes groff to hang unless I take unusual measures. A simple demo:
groff -pspic /dev/null
Looking deeper, I am surprised to find pic running--I can't
imagine why. Apparently some process is trying to read
standard input. It can be satisfied by giving it an eof:
groff -pspic /dev/null </dev/null
Can anybody offer insight into what's happening, or whether
the phenomenon is replicable?
