Hello, I am trying to move a project of mine from gcc-3.1 to gcc-3.3 under MacOS X Jaguar. I'm using Apple's developer tools with the December 2002 updater which included gcc-3.3. Everything compiles just fine under 3.1 but I really need to use precompiled headers which does not work very well. I have managed to precompile my prefix header using 3.3 and I can also compile most of my source files using it. However, as soon as the compiler encounters a source file where Boost.Function is used I get an internal compiler error. So, I wrote a small program (included at the end of this email) which demonstrates the error. It works just fine under 3.1 but not under 3.3. Using preferred or portable syntax makes no difference. Has anyone else experienced this problem, or has it been fixed in Xcode? Perhaps I'm just doing something wrong? I'd really like to know before I file a bug. (I did a couple of searches on lists.boost.org but didn't find anything of interest.) Thanks in advance, Jens ------------------------------------------------------------ #include <iostream> #include void test( int x ) { std::cout << x << std::endl; } int main( int argc, char* argv[] ) { boost::function __test(test); __test(5); return 0; } ------------------------------------------------------------ Which gives the following error: /Development/Libraries/boost-1.30.2/boost/function/ function_template.hpp: In member function `void boost::function1::assign_to(FunctionPtr, boost::detail::function::function_ptr_tag) [with FunctionPtr = void (*)(int), R = void, T0 = int, Allocator = std::allocator<void>]': /Development/Libraries/boost-1.30.2/boost/function/ function_template.hpp:432: instantiated from `void boost::function1::assign_to(Functor) [with Functor = void (*)(int), R = void, T0 = int, Allocator = std::allocator<void>]' /Development/Libraries/boost-1.30.2/boost/function/ function_template.hpp:293: instantiated from `boost::function1::function1(Functor, typename boost::detail::function::enable_if::value>::value, int>::type) [with Functor = void (*)(int), R = void, T0 = int, Allocator = std::allocator<void>]' /Development/Libraries/boost-1.30.2/boost/function/ function_template.hpp:602: instantiated from `boost::function::function(Functor, typename boost::detail::function::enable_if::value>::value, int>::type) [with Functor = void (*)(int), R = void, T0 = int, Allocator = std::allocator<void>]' test.cpp:12: instantiated from here /Development/Libraries/boost-1.30.2/boost/function/ function_template.hpp:451: internal compiler error: in c_expand_expr, at c-common.c:4752 Please submit a full bug report, with preprocessed source if appropriate.
