perl debugger hangs when output is viewed via a pager

This document (3382989) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 10
SUSE Linux Enterprise Desktop 10

Situation

The perl debugger hangs when the output is piped into a pager such as less and that pager is exited, e.g. when running

perl -d script.pl | less

Resolution

Since control-C is ignored,often you can use control-Z to suspend the process and then kill it

kill %1

Sometimes the hung debugger also ignorescontrol-Z; the process then needs to be killed from a separate login.

This isssue has been reported to Engineering and is expected to be fixed in the next Service Pack for the affected products.
