example (based on hello-jni) to reproduce the problem.
Our example project can be downloaded here:
http://bit.ly/yaHBEL and
then installed with, e.g.
android update project -p .
ndk-build -B NDK_DEBUG=1
ant all clean debug install
The relevant content of the project is listed below.
Note that the crash only occurs on TEGRA devices and when the native
code is compiled with NDK r7b (everything works with r7).
The immediate trigger of the SIGILL crash seems to be the use of a
cmath function on a volatile floating point variable. Making the
variables non-volatile or substituting <cmath> by <math.h> will fix
the issue in this particular example.
The below code will produce a crash, but there seem to be other not-so-
clear ways to make it crash, too. In our production code, for example,
we are not using 'volatile', yet it crashes with
Stack frame #00 pc 00002db4 /data/data/com.X/lib/libX.so (sinf):
Unable to locate routine information for address 2db4 in module ./obj/
local/armeabi-v7a/libX.so
As a result, we currently don't have a workaround for the issue,
besides reverting to use of NDK r7.
I hope the provided example will help to identify and fix the problem.
Best,
Michael

These are Android.mk and Application.mk. but these project are really
different, using different rendering engine. Everything work very fine with
r7, but crash with r7b.
'm really not doing anything fancy.

The math library doesn't use NEON. What's surprising is that there
seems to be a copy of cosf / powf inside your own shared library.
How do you build this exactly?

(very wild guess : I'm testing on a TEGRA chipset, is there any
way that the libmath ( or whatever ) is using NEON ? It works find if I
switch back to r7.
