What really puzzles me is why some firefox issues seem to affect

in the last couple of months when I upgraded firefox (I no longer
remember the details, but I think it was a specific version of gcc which
caused it) and found one open firefox bug showing the exact problem.
But a lot of people build firefox on, or
for, old systems using i686 or x86_64 (e.g. distros do it!) and nobody
else had seen the problem.
For what it is worth, I think my crashes maybe/could/are likely
connected to the xcb backend of cairo. I used --enable-xlib-xcb with cairo
and the patch which fixes it for me is patching code for xcb.

So perhaps those two of you which also have crashes did enable xcb also?

Hello Thorsten,

I did indeed use the --enable-xlib-xcb compile option with cairo.  Not
sure which window managers require this, but I thought it prudent to
actually enable it rather than have to re-compile down the track.  I also
used the
--enable-gl switch, as I am building full gnome and that is one of the
requirements for wayland.

So yep there are two experimental backends enabled in cairo.

Regards,

Christopher.


Also, I see you use LFS svn from the "systemd era". Was the GCC-4.9.0 patch already in there? I think you need it to avoid weird errors. For example, I have had some hard time with openjdk (test_gamma hanging) with an unpatched GCC. Rebuilding it with the patch (using instructions in BLFS), solved the problem.

Regards
Pierre
