Sourceware 18035 0 P2 RESOLVED pldd does no longer work, enters infinite loop 2020-08-24 13:17:42 UTC

Description Yaakov Selkowitz 2016-07-29 18:41:56 UTC 
Just ran into https://sourceware.org/bugzilla/show_bug.cgi?id=18035 :

$ pldd $$
4938:    /usr/bin/bash

then it hangs.  According to the upstream bug, this has been broken since 2.19.
Comment 1 Carlos O'Donell 2016-07-29 20:02:52 UTC 
This bug is open upstream and we're not going to to fix this in Fedora unless upstream fixes it. Please continue the discussion upstream.

As a workaround you can use gdb:

cat >> pldd.sh <<EOF
#!/bin/sh
gdb -ex "set confirm off" -ex "set height 0" -ex "info shared" -ex "quit" -p $1 | grep '^0x.*0x'
EOF

This needs gdb and grep.

The purpose of pldd is to print the list of shared objects in use by the application in question. It's useful in some instances when gdb might not be stable, but that seems like a really small use case.
Comment 2 Carlos O'Donell 2016-07-29 20:06:55 UTC 
For the record I've recommended upstream deprecate and remove pldd.
Comment 3 Yaakov Selkowitz 2019-04-23 22:23:52 UTC 
A supposed fix was just committed upstream:
