internal compiler error backtrace
I have some Fortran 2003 code, hosted here:
https://github.com/danshapero/sigma
It builds and passes all tests on gfortran-4.7.2 and 4.8.2 on Intel 32, AMD64
and ARM with Linux, and Intel/OSX.
I'm attempting to build it with gfortran-5.0, because co-arrays :D.
Unfortunately, I'm getting an internal compiler error. GCC was configured with
../configure --prefix=/home/daniel/programs/gcc --enable-languages=c,fortran
--enable-checking=release --disable-bootstrap
--disable-build-poststage1-with-cxx --disable-libstdcxx-pch --disable-multilib
in accordance with the suggestions from
https://gcc.gnu.org/wiki/GFortranBinaries#FromSource. The GCC test suite
passes, and I've compiled some simple programs to verify that gfortran-5.0
works.
The backtrace is long; I've attached it as a text file. The library is built
with the usual
mkdir build
cd build
FC=gfortran-5.0 CC=gcc-5.0 cmake ..
make
The error also occurs when I do a debug build that includes -Wall -Wextra.
I can attempt to make a reduced test case for this, but I'm a bit out of my
depth here. Thanks for reading!
