retitle 686231 dragonegg-4.6 built incorrectly - internal compiler error:
Segmentation fault with llvm-gcc / cpp-4.6 4.6.3-9
severity 686231 serious
thanks
Raising severity because llvm-gcc is unusable and its build is
incorrect (was it built in an incorrect environment or is there
any missing build dependency?), meaning that it can yield obscure
problems.
If I rebuild and reinstall dragonegg-4.6 (still version 3.1-2)
locally with:
$ apt-get source dragonegg
$ cd ./dragonegg-3.1
$ dpkg-buildpackage -b -uc
$ su
# dpkg -i llvm-gcc-4.6_3.1-2_amd64.deb dragonegg-4.6_3.1-2_amd64.deb
dragonegg_3.1-2_amd64.deb
the problem disappears (I've tested with valgrind too in case there
were still a hidden incorrect memory access, but everything is fine).
If I reinstall the official binaries with:
# apt-get install dragonegg-4.6 dragonegg llvm-gcc-4.6
the problem (segmentation fault) reappears.
If I copy the correct dragonegg.so in a safe place, and use
"gcc-4.6 -fplugin=.../dragonegg.so" after the above apt-get,
the problem doesn't occur:
$ gcc-4.6 -fplugin=/home/vlefevre/software/dragonegg.so -c test.i
$ gcc-4.6 -fplugin=/usr/lib/gcc/x86_64-linux-gnu/4.6/plugin/dragonegg.so -c
test.i
