Bug ID: 57524 Summary: internal compiler error on dump translation unit Product: gcc Version: 4.7.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: JamesMikeDuPont at googlemail dot com using the debian sid standard : GNU C++ (Debian 4.7.2-5) version 4.7.2 (x86_64-linux-gnu) compiled by GNU C version 4.7.2, GMP version 5.0.5, MPFR version 3.1.0-p10, MPC version 0.9 warning: MPFR header version 3.1.0-p10 differs from library version 3.1.1-p2. GGC heuristics: --param ggc-min-expand=100 --param ggc-min-heapsize=131072 Compiling boost spirit.qi code, Here is the one that creates the error. Invocation is : /usr/lib/gcc/x86_64-linux-gnu/4.7/cc1plus -std=gnu++11 -fdump-translation-unit treedumpparse.ii the output is: (this is the last of the function print ) std::size_t boost::detail::variant::variant_hasher::operator()(const T&) const the error is : In file included from /usr/include/boost/variant/variant.hpp:35:0, from /usr/include/boost/spirit/home/support/info.hpp:14, from /usr/include/boost/spirit/home/qi/domain.hpp:16, from /usr/include/boost/spirit/home/qi/meta_compiler.hpp:15, from /usr/include/boost/spirit/home/qi/action/action.hpp:14, from /usr/include/boost/spirit/home/qi/action.hpp:14, from /usr/include/boost/spirit/home/qi.hpp:14, from /usr/include/boost/spirit/include/qi.hpp:16, from treedumpparse.cpp:6: /usr/include/boost/variant/detail/hash_variant.hpp:32:33: internal compiler error: in timevar_start, at timevar.c:344 Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-4.7/README.Bugs> for instructions. This can be reproduced with this one include : #include "/usr/include/boost/variant/detail/hash_variant.hpp" I am trying to reduce the problem, but it is difficult.
