Can you post a backtrace? It would be useful if the build used -fno-inline, or
this will get a bit tricky to track down.

Please also verify that Qt did detect that Neon is absent. Run libQtCore.so.4
and paste the last line of the output. E.g.:

# /usr/lib/libQtCore.so.4
This is the QtCore library version 4.7.1

Build key: armv6 linux g++-4 full-config
Compat build key: |
Build date: 2010-11-04
Installation prefix: /usr
Library path: /usr/lib
Include path: /usr/include/qt4
Processor features: neon

If it says "neon" is present (like above), then it looks like there was a
detection mistake. Can you try turning the feature off by setting
QT_NO_CPU_FEATURE=neon and running the app again?

Finally, it would be nice also to have the command-line of the compiler used
when compiling the actual .cpp file.
