Version-Release number of selected component (if applicable):
boinc-manager-5.10.45-9.20080315svn.fc9.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Run `boincmgr`

Comment 1 Milos Jakubicek 2008-05-09 21:13:51 UTC
What version of wx widgets (wxGTK package) do you have installed?

Comment 2 Luke Macken 2008-05-10 00:20:09 UTC
wxGTK-2.8.7-2.fc9.x86_64


Comment 3 Milos Jakubicek 2008-05-10 22:07:16 UTC
I can confirm this behaviour on F9 -- but it seems to be caused by wxWidgets,
therefore I'm changing the component to wxGTK. 


Comment 4 Dan Horák 2008-05-12 08:52:41 UTC
It is questionable what is the primary source of the problem, because there is
no problem when I try to run boincmgr on F9/i386. Also boinc* packages have
unusable debuginfo, so it is hard to debug.

Comment 5 Milos Jakubicek 2008-05-12 09:37:08 UTC
Luke, are you running an i386 or x86_64 machine?
(I'll try to investigate what's wrong with the debuginfo package.)

Comment 6 Dan Horák 2008-05-12 09:58:59 UTC
The source of missing debuginfo is probably simple - strip (resp. @STRIP@) is
run when creating/symlinking ".unmodified" and normal binary - see the end of
Makefile.am in both client and clientgui dirs.

x86_64

Comment 8 Milos Jakubicek 2008-05-13 09:46:47 UTC
It happens only on x86_64 -- even installing i386 packages on F9/x86_64
(including all its dependencies, of course) makes boincmgr working.

I've fixed the broken debuginfo package (thanks for the hint, I should have
noticed earlier that it is so damn small) -- please download the latest build
from Koji:

http://koji.fedoraproject.org/koji/buildinfo?buildID=48824

So the current gdb output is:

Comment 9 Dan Horák 2008-05-13 14:27:42 UTC
From the backtraces #2 and #1 is clear that problem is in boincmgr - #2 calls #1
with this=0x0 (m_SimpleSkin member of the class should be NULL when his method
gets called).

boinc-manager works on F8/x86_64 + wxGTK-2.8.7-2, so it looks like a gcc 4.3
incompatibility of the boincmgr's sources, switching the component back to
boinc-client

Comment 10 Bug Zapper 2008-05-14 10:55:55 UTC
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:

Comment 11 Milos Jakubicek 2008-05-16 10:53:28 UTC
I see, sorry -- somehow I thought that from #3 down it's wxWidgets code,
although SkinManager.cpp is a part of BOINC.

Reported into BOINC trac as ticket #658 
(http://boinc.berkeley.edu/trac/ticket/658)

Comment 12 Bradley 2008-05-16 14:41:59 UTC
This bit me; I got a simplified test case and have attached a fix to the boinc bug.

sizeof(int) != sizeof(long) - this should never have worked....

Not sure the best way to get upstream to apply this; I'll leave that with you....

Comment 13 Bradley 2008-05-17 03:50:13 UTC
Its been applied upstream.

Comment 14 Milos Jakubicek 2008-05-17 10:02:02 UTC
Great work Bradley, thank you very much!

Should be fixed in boinc-client-5.10.45-13.20080315svn.fc9

(http://koji.fedoraproject.org/koji/buildinfo?buildID=49385)

An update will come soon.

Comment 15 Bradley 2008-05-17 10:52:35 UTC
Yep, that fixes it.
