Here also segfault on startup on ~amd64, but unsupported toolchain (glibc-2.6,
gcc-4.2.0).

Well, in order to get a meaningful bug report to upstream developer, a
backtrace is needed. Here's a link which explains how to get a good backtrace:
http://www.gentoo.org/proj/en/qa/backtraces.xml

Created an attachment (id=123705) [details]
backtrace.log

Attached my backtrace. It's from my ~amd64 system with glibc-2.6 and qt-4.3.0.

I really want to give a backtrace, but when I run qmpdclient in gdb I only get
te following:

And then nothing. Not an gdb prompt or anything else. So I think you should use
Bens stacktrance.

Now respects user's C(XX)FLAGS and LDFLAGS. Thanks a lot to Flameeyes on IRC
for helping.

Thanks, all.

OK, I've added 1.0.8 (latest ebuild from Davide with some minor changes) to
CVS. I have dropped ~amd64 keyword, and am assigning this bug to amd64 team,
since it definitely seems to be arch-specific.

1.0.8 works fine for me on amd64. Just emerged.

I think I've found the bug and I have a patch.

Improved ebuild with patch

qmpdclient-1.0.8-argc-ref-fix.patch

Thanks for the patch! It now works perfectly on ~amd64 with qt-4.3.0 as well as
qt-4.2.3.

Thanks, patch is now applied to 1.0.8.

amd64, can you please readd your ~keyword to media-sound/qmpdclient-1.0.8 ?

Please note that I have added QMAKE_LINK variable to the command line of qmake
in the last attached ebuild. Please add it to the ebuild in portage, thanks.

amd64@, can you please test and re~keyword?
