gcc stderr
I build a python package, matplotlib 1.4.3, obtainable at
https://github.com/matplotlib/matplotlib/archive/v1.4.3.tar.gz
The call to `python2 setup.py build` in the extracted directory leads to this
call:
gcc -pthread -fno-strict-aliasing -march=x86-64 -mtune=generic -O2 -pipe
-fstack-protector-strong -fno-plt -DNDEBUG -march=x86-64 -mtune=generic -O2
-pipe -fstack-protector-strong -fno-plt -fPIC
-PY_ARRAY_UNIQUE_SYMBOL=MPL_matplotlib__png_ARRAY_API -DPYCXX_ISO_CPP_LIB=1
-I/usr/lib/python2.7/site-packages/numpy/core/include
-I/usr/lib/python2.7/site-packages/numpy/core/include -I/usr/include/libpng16
-I/usr/local/include -I/usr/include -I. -Iextern -I/usr/include/python2.7 -c
src/_png.cpp -o build/temp.linux-x86_64-2.7/src/_png.o
This call leads to the output:
src/_png.cpp: In member function ‘Py::Object _png_module::write_png(const
Py::Tuple&)’:
src/_png.cpp:103:12: internal compiler error: Segmentation fault
Py::Object _png_module::write_png(const Py::Tuple& args)

Please find the full output (with -v -save-temps) attached, as well as the
corresponding .ii file.
