[Qemu-devel] [Bug 1077116] Re: automoc4 segfaults when building in an armhf pbuilder on an amd64 host

[Serge Hallyn]

Thanks for reporting this bug.  There seem to be a few bugs in the armhf
qemu-user-static right now.  I'll test against bleeding edge upstream.

Bug description:
  When trying to build kde4libs in an armhf pbuilder created with the
  pbuilder-scripts running on an amd64 host automoc4 recieves a
  segmentation fault and I can't get any useful information out of it:

  automoc4 runs fine when building on a nexus7 so this sounds like an issue in 
qemu.
  Tested in quantal and raring.
