Hello Tobin, or anyone else affected,
Accepted soprano into natty-proposed, the package will build now and be
available in a few hours. Please test and give feedback here. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed. Thank you in advance!

Yes, I can reproduce this crash with some kde workspace applications
that use the soprano library (kactivitymanagerd,
akonadi_nepomuk_contact_feeder, nepomukserver). I did a local rebuild of
soprano using the gcc/qt4 versions that ship with natty and the problem
was fixed.

I think I met a similar problem as mentioned in this thread.
What I do:
- use linaro image with toolchain Ubuntu/Linaro 4.5.2-3ubuntu2 on imx51
- apply the IT patch, and build latest mainline qt locally on imx51 with gles2
enabled (-opengl es2)
- when run qtdemo and some other qt examples,

Thanks to Dave for the excellent debugging work here, pinpointing the
RTL instruction that wrongly gets deleted.
The instruction is being deleted by a delete_trivially_dead_insns call
during IRA. Surprisingly for such an old function, the bug seems to be
in d_t_d_i itself. count_reg_usage

Michael, yes I am referring to that constuctor; Only QGestureRecognizer is
mentioned because the constructor's symbol is not in the binary apparently.
I could only locate the exact spot of the crash in by putting asm volatile(mov
r5,r5) and similar eyecatchers, as most functions there are
Michael, in the disassembly output you have attached the lines starting
at 442 are the one comparing metatype_id to 0, then returning
metatype_id and that corresponds to the snippets I have pasted earlier.

Hi Jani. Could you clarify some things please?
You mention the QGestureManager constructor, but the disassembly
mentions GestureRecognizer. Are you referring to
QGestureManager::QGestureManager(QObject *parent) at
src/gui/kernel/qgesturemamanger.cpp:73?
You mention Q_DECLARE_METATYPE, but I
