pango @1.26.0_0+macosx makes software freeze

[vinc17@…]

After upgrading from pango @1.24.5_0+macosx to pango @1.26.0_0+macosx, at least two applications based on pango started to freeze, without any error message: liferea (the window didn't appear) and a Perl script using rrdtool (freezing and taking 100% CPU time, probably in RRDs::graph).

The only thing I can do about that is report it to the pango developers, so it would be more efficient for you to do so, since you can better describe the problem and test possible fixes.

[vinc17@…]

OK, I'll do that (since this is always reproducible, I can try to look at traces and so on). But it would be interesting to know if other users can reproduce the problem too, and on which OS X version.

I have Mac OS X 10.4.11 / PowerPC.

I have some unexplained problem where a number of applications have slowed to a crawl when I try to start them up. I've seen issues with 'gnubg', 'gimp2', and 'inkscape'. I've also suspected that the underlying issue is from pango. I've also had the problem on two different computers. I can't put any more exact description on the problem, but it is more than annoying.

[ryandesign@…]

Please report these issues to the developers of pango.

Possibly this is  https://bugzilla.gnome.org/show_bug.cgi?id=593240

I just reported ticket #21679 which seems to be the same problem. There is a sample of a hanging inkscape there.

[ryandesign@…]

I've reverted the pango port back to 1.24.5 (r58513) until the developers of pango figure out how to fix this.

[ryandesign@…]

Has duplicates #21678, #21679, #21701. Was also reported several times  on  the  mailing  list.

Has duplicate #22054 (requested update to 1.26.0; referred back here explaining why we can't right now).

The  upstream bug report now indicates this appears to be an incompatibility with Apple's gcc; it allegedly works fine with normal gcc. So we could possibly make pango compile using, say, the gcc44 port. But I don't know what impact that would have on other ports -- e.g., would ports that want to link with pango also have to use gcc44? If so, that wouldn't be an acceptable solution since half the known universe depends on pango.

Gtk-demo was freezing for me. Adding "configure.compiler macports-gcc-4.3" to pango's Portfile fixed this. Obviously, this is not a permanent solution. However, it does seem to support the upstream diagnosis.

[mike@…]

This Portfile worked for me:  http://trac.macports.org/attachment/ticket/17049/Portfile. As far as I can tell I this Portfile builds pango using Apple's gcc.

[jeremyhu@…]

The upstream bugzilla mentions a patch that might fix this. I'm testing.

[jeremyhu@…]

And it seems ineffective...

This should fix itself when we upgrade pango to 1.26.x, because we then won't use the muniversal portgroup anymore. But we can't upgrade to 1.26.x right now because it causes problems. For now, it looks like you cannot install pango 1.24.5 universal with quartz. I could possibly work around this by looking at how pango 1.26.0 generates its libpangocairo-1.0.la file when building universal with quartz, and apply that to 1.24.5's file.

I tried building 1.26.0 (may try 1.26.2 in a bit) using the Portfile attached to #21624, but I get the same error. I commented out the PortGroup muniversal 1.0 line and then pango and GTK2 built +no_x11 +quartz. I'm hoping to go on to build gq then to try to build workrave using the instructions here:  http://old.nabble.com/How-I-got-1.9.0-compiled-on-Mac-OS-X-10.6-(-Snow-Leopard)-td25547590.html I can't get openldap to build, which is unrelated, but is stopping me building gq to see if GTK2 works at all. After I've prodded about a bit I'll file a bug against the openldap port (I couldn't find anything like openldap +universal x86_64 fails to build )

OK, Ryan Schmidt kindly fixed up the openldap port, so I could build gq with my altered portfile. It runs, but the underlined letters in the menus look odd, and it crashes a lot. I'll try with 1.26.2. (How does one compute rmd160 checksums?) Right, rebuilt pango. port doesn't seem to think gtk2 and gq need to be rebuilt.

I've attached the crash report details from when I press the "Options" button.

This should be working for pango-devel as of r64195
