Error is in libpcp_qmc with the error reporting logic on these two error paths. Commit 01f8aea in my tree contains fixes for each of these.

Marko, where did your rpms come from and for what platform? I suspect the rpm build is bad, rather than a system PCP 3.9.10 issue. I have pmdumptext in 3.9.10 images for at least the following (there may be others, these are the QA VMs that are up at the moment) Date Run Pass Fail Nrun Host 2014-09-04 687 672 15 50|bozo PCP 3.9.10 x86_64 Ubuntu 14.04 2014-09-02 674 660 14 62|bozo-laptop PCP 3.9.10 i686 LinuxMint 15 Daily runs, but no QA |bozo-vm PCP 3.9.10 x86_64 Debian 7.5 2014-09-05 679 668 11 60|vm00 PCP 3.9.10 x86_64 Ubuntu 12.04 2014-09-05 671 662 9 68|vm01 PCP 3.9.10 i686 Ubuntu 12.10 2014-09-05 678 673 5 61|vm03 PCP 3.9.10 x86_64 Fedora 18 2014-09-07 673 663 10 66|vm14 PCP 3.9.10 x86_64 CentOS6.5 2014-09-07 660 646 14 79|vm22 PCP 3.9.10 x86_64 Fedora 19 2014-09-08 678 663 15 61|vm23 PCP 3.9.10 i686 Fedora 20
Hi Ken, I'm on 64-bit RHEL 6 using this EPEL build: http://koji.fedoraproject.org/koji/buildinfo?buildID=575413 Thanks.
Looks like that build is bad. The closest thing I have is ... kenj@vm14:~$ cat /etc/redhat-release CentOS release 6.5 (Final) with rpms I made myself from Makepkgs kenj@vm14:~$ rpm -q -f /usr/bin/pmdumptext pcp-gui-3.9.10-3.x86_64 Ahh ... you need to install the pcp-gui rpm, not just pcp ... is that the problem?

Ah, thanks, that's it. I was testing on a system which had no pcp-gui, usually I have it installed and I didn't think pmdump*text* would be part of pcp-*gui* package :) Wrt the segfault, I'm happy to confirm it's fixed. Thanks.
It is part of pcp-gui because is uses the same metrics class libraries that the gui tools (pmchart et al) use. Does not have to be this way, but it just "is".
