This was reported on gcc-bugs by James W. McKelvey (mckelvey at maskull com),
but I can't find it in the database. According to James, it also occurs on
Solaris 2.7.1. It does not occur with 3.3 or earlier.

Here's an unpreprocessed test case:

#include <vector>

namespace PatternMaster {
    struct SymbolTable {
	static const bool EMPTY_BOOLEAN = false;
    };
}

bool evaluate(std::vector<bool> value) {
    const unsigned long offset = 23;
    return (offset < value.size()
	    ? value[offset]
	    : PatternMaster::SymbolTable::EMPTY_BOOLEAN);
}

% g++ --version             
g++ (GCC) 3.4 20030614 (experimental)
% g++ -c bugs.cc            
bugs.cc: In function `bool evaluate(std::vector<bool, std::allocator<bool> >)':
bugs.cc:13: internal compiler error: in build_conditional_expr, at cp/call.c:
