           Version: 4.8.0

Created attachment 26933
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26933
C++ source code

I just tried to compile the package lpg-1.1.0
on gcc-4.8 trunk dated 20120319 on an AMD x86_64 box.

The compiler said

In file included from generator.h:4:0,
                 from generator.cpp:1:
tuple.h: In constructor 'Array<T>::Array(int, T) [with T = bool]':
tuple.h:28:5: internal compiler error: in build_vector_from_val, at tree.c:1386
Please submit a full bug report,
with preprocessed source if appropriate.
