Yep... (gdb) print ent $1 = (struct plt_entry *) 0x0
ent = find_plt_ent (ifunc, got2, addend); if (ent->plt.refcount > 0) ent->plt.refcount -= 1; does not check for the returned ent being null.
Looks like a binutils bug, Cc'ing toolchain for advice.
Note that this does not happen with webkit-gtk, only the Qt version.
Can confirm this on my G4 PPC 32.
Still fails with gcc 4.4.3
Have you tried with binutils-2.20.51.0.6 ?
I just tried binutils-2.20.51.0.6 and to my surprise it worked :-)

After doing this, qt webkit compiled and installed without issues.
That version of binutils is not keyworded :-( Installing it by using ** does work though and it allows qt-webkit to be built. Can that version please be keyworded ~ppc?

The user kindly offered us links to backport the patches to the stable binutils branch, why should we keyword a experimental version then?
Thanks. Patch queued for 2.20-r1.

Hi All, Could anybody please clarify, why this bug is a blocker for Qt 4.6 stabilization? As I understand this issue can be reproduced only with latest unstable binutils and only on ppc platform. So it's not related to current stable profiles.

That is true and for that reason this is only a blocker for Qt 4.6 stabilization on ppc. Stabilization for the other arches will go ahead, as planned, next week.
(In reply to comment #21) > I don't see any indication in this bug that it works with 2.18 or 2.19 So you mean that the Qt 4.6 cannot be built on ppc at all? I think in this case the bug description is ambiguous, because it looks like only 2.20 branch is affected. > That is true and for that reason this is only a blocker for Qt 4.6 > stabilization on ppc. Stabilization for the other arches will go ahead, as > planned, next week. Wow, great.
In the tree.
qt-webkit-4.6.2 is stable on ppc, but newer binutils is not, thus users are hitting this bug in the stable tree.
