             Bug #: 55349
           Summary: arm-linux-androideabi-gcc-4.6: Internal compiler error
                    compiling libpng in debug mode
    Classification: Unclassified
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ibenrunnin@gmail.com


Firstly: ndk-build doesn't give output of which version of gcc it is using but
looking in the toolchains folder I checked the version number of what I believe
it is running:
arm-linux-androideabi-gcc-4.6 (GCC) 4.6 20120106 (prerelease)

Here is information regarding the issue, which should be enough to reproduce
the problem:

Please describe the problem in detail, with the following information (if
applicable)
Host OS:Linux
NDK tools version: tested with android-ndk-r8b and android-ndk-r8c

STEPS TO REPRODUCE:
(Tested using android-ndk-r8b and android-ndk-r8c, libpng 1.2.38 and 1.5.13)
1.Setup simple NDK dev environment with libpng 1.5.13
2.run NDK_DEBUG=1 ndk-build
3.build will fail

EXPECTED RESULTS:
For libpng to compile successfully (which it does when NDK_DEBUG is set to 0)

OBSERVED RESULTS:
Compile thumb  : png <= pngrtran.c
jni/png/pngrtran.c: In function 'png_do_rgb_to_gray':
jni/png/pngrtran.c:3418:1: internal compiler error: in reload, at
reload1.c:1061
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make: *** [obj/local/armeabi/objs-debug/png/pngrtran.o] Error 1


^It is therefore reasonable to conclude that this is a bug within NDK or
perhaps the version of GCC it is using.
