gcc 4.8 internal compiler error: in add_stores, at var-tracking.c:5918

btw this is the version of linaro gcc

Hi Khem,

Would you please attach configure line from "arm-angstrom-linux-gnueabi-g++ -v" output?

Thank you,

This seems to be a recent regression; I don't hit the ICE with linaro gcc 4.8-2014.01

I am unable to confirm this bug with linaro gcc 4.8.3 20140401 prerelease.

Cannot reproduce.

I have also hit the same problem during compilation of Angstrom image + QT5 for Apalis iMX6 module. Not sure why exactly the compiler is crashing, but it seems that this patch solves the problem.

http://pkgs.fedoraproject.org/cgit/mingw-qt5-qtbase.git/tree/qt5-workaround-gcc48-arm-build-failure.patch?h=f20

This problem is still reproducible on linaro-4.8-branch as of yesterday.

I'm unable to reproduce the problem with:

gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux/bin/arm-linux-gnueabihf-g++ -march=armv7-a -marm -mthumb-interwork -c -O2 -g -std=c++0x -fno-exceptions -fPIE a.cpp

and

gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux/bin/arm-linux-gnueabihf-g++ -march=armv7-a -marm -mthumb-interwork -c -O2 -g -std=c++0x -fno-exceptions -fPIE a.cpp

Doing something wrong?

I am now able to reproduce with the latest linaro 4.8. I have a patch which I am now testing.

Now tracked at https://bugs.linaro.org/show_bug.cgi?id=534
