another gawk 3.1.2 bug

[John H. DuBois III]

Under SCO OpenServer 5.0.6a and linux, this program:

BEGIN{cmd = "cat /etc/termcap"; cmd | getline; print close(cmd); }

(where /etc/termcap is any file large enough that it will not fit in pipe
buffers)

correctly prints 141 (process killed by SIGPIPE) under gawk 3.1.1.
Under gawk 3.1.2 (built with gcc 2.95.3 & 3.2.2), it prints 13; the high bit
(indicating that the process exited due to receipt of a signal) is being lost.

Some further problems with the return value from close:

$ gawk-3.1.2 'BEGIN{cmd = "exit 1"; cmd | getline; print close(cmd); }'
256

$ gawk-3.1.2 'BEGIN{cmd = "exit 2"; cmd | getline; print close(cmd); }'
512
