CrystaX NDK

When building standalone executables with Crystax 10.2.1 and running these on an Android Marshmallow (API 23) emulator, they crash after the main() method returns. There's always one of two messages (non-deterministic):

Invalid address 0xb6eead84 passed to free: value not allocated
Aborted

or

Segmentation fault

Here's my test program:

int main(int argc, char **argv) {}

I tested all combinations of the following:

• NDKs: Google, CrystaX
• Compilers: gcc 4.8, gcc 4.9, clang 3.5, clang3.6
• Archs: armv7-a, x86
• STLs: gnustl, libcxx
• Android emulator APIs: 22, 23

All tests with Google's NDK or with Android 22 were fine, but all tests combining CrystaX and Android 23 showed the error.

I added my test scripts as an attachment. You use them as follows:

• extract CrystaX NDK and the official Android NDK to /opt/crystax-ndk and /opt/android-ndk
• change to the testproject dir from my tarball
• ./make-toolchains.sh # this takes around 12 GB of space!
• ./buildall.sh
• start an emulator (armv7-a or x86)
• adb push PATH_TO_LIB/libcrystax.so /data/local/tmp
• ./runall.sh x86 # or ./runall.sh armeabi-v7a

You will get the following output for API 23 x86:
