libc6 2.13 causes segfaults/illegal instructions on tegra/armel

Bug Description

I have been working on getting natty working on a nvidia tegra2 based tablet (Advent Vega)
Maverick works fine, but after upgrade to natty many things fail with segfaults or Illegal instruction messages.
It fails more reliably with gtk and qt applications but many other apps fail (such as aptitude)
Core X applications (such as xterm) tend to work though.
When seen the following two lines turn up in messages log:

Alignment trap%3A not handling instruction e8524f00 at [<407b4dfa>]
Unhandles fault: alignment exception (0x011) at 0x42f824a5

This has been tested with 2.13-0ubuntu2 and 2.13-0ubuntu3 with no change
If I revert to libc6 2.12.1-0ubuntu10.2 packages then everything works again (showing the problem is in libc rather than libgtk or libqt)

This still occurs with 2.13-0ubuntu7 and is even more of a problem since more things now rely on 2.13 due to recent multiarch changes

Does this still happen in precise?
