[Speex-dev] Speex crashing on ARM with assembler optimization enabled.

[Jean-Marc Valin]

Did you test what happens if you only enable arm4 assembly? Also, if you
can do some investigation, it would be useful to check what bit of
assembly is causing the crash. Can you disable one at a time and check?
