Hello,

Does anyone know a workaround to the problem of compiling the Pydolfin
file dolfin_wrap.cc with mpicxx version 4.3.1? I get several warnings
during compile, and segmentation faults at runtime. I am using Debian
Lenny, which uses 4.3.1 as the default compiler. SWIG is version
1.3.33. Any help in this matter would be greatly appreciated.

Here are the errors when enableDebug=no:
