Subject: In forked children, set SIGPIPE to SIG_DFL.
|
|
|
|
---
|
|
* io.c (two_way_open): In forked child, reset SIGPIPE to SIG_DFL.
|
|
Fixes problems with "broken pipe" errors from child processes,
|
|
restoring 4.1.0 and earlier behavior. Thanks to Daryl F
|
|
<wyatt@prairieturtle.ca> for the report.
|
|
(gawk_popen): Ditto.
