I just tried to compile the Suse Factory package Botan-1.6.4-4.48 with the GNU g++ version 4.5 snapshot 20090604.
The compiler said modules/es_unix/es_unix.cpp:106:1: error: missing callgraph edge for call stmt: # VUSE <.MEM_16> retval.72_11 = Unix_Program_Cmp (__val_10(D), __next$_M_current_3); void std::__unguarded_linear_insert(_RandomAccessIterator, _Tp, _Compare) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator<Botan::Unix_Program*, std::vector<Botan::Unix_Program> >, _Tp = Botan::Unix_Program, _Compare = bool (*)(const Botan::Unix_Program&, const Botan::Unix_Program&)]/473(-1) @0x2ba81fb0d000 (inline copy in void std::__insertion_sort(_RandomAccessIterator, _RandomAccessIterator, _Compare) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator<Botan::Unix_Program*, std::vector<Botan::Unix_Program> >, _Compare = bool (*)(const Botan::Unix_Program&, const Botan::Unix_Program&)]/558) (clone of void std::__unguarded_linear_insert(_RandomAccessIterator, _Tp, _Compare) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator<Botan::Unix_Program*, std::vector<Botan::Unix_Program> >, _Tp = Botan::Unix_Program, _Compare = bool (*)(const Botan::Unix_Program&, const Botan::Unix_Program&)]/482) availability:local 390 time, 17 benefit 29 size, 8 benefit body local finalized inlinable called by: void std::__insertion_sort(_RandomAccessIterator, _RandomAccessIterator, _Compare) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator<Botan::Unix_Program*, std::vector<Botan::Unix_Program> >, _Compare = bool (*)(const Botan::Unix_Program&, const Botan::Unix_Program&)]/558 (21.97 per call) (inlined) (can throw external) calls: std::basic_string<_CharT, _Traits, _Alloc>& std::basic_string<_CharT, _Traits, _Alloc>::assign(const std::basic_string<_CharT, _Traits, _Alloc>&) [with _CharT = char, _Traits = std::char_traits<char>, _Alloc = std::allocator<char>]/707 (21.97 per call) (nested in 1 loops) (can throw external) std::basic_string<_CharT, _Traits, _Alloc>& std::basic_string<_CharT, _Traits, _Alloc>::assign(const std::basic_string<_CharT, _Traits, _Alloc>&) [with _CharT = char, _Traits = std::char_traits<char>, _Alloc = std::allocator<char>]/707 (100.00 per call) (nested in 2 loops) (can throw external) modules/es_unix/es_unix.cpp:106:1: internal compiler error: verify_cgraph_node failed Please submit a full bug report, with preprocessed source if appropriate.
