Windows 2000, MinGW 2.0.0-3, Spirit 1.5.1 (latest CVS)
>Description:
You can download the file from here:

http://home.JCABs-Rumblings.com/ftp/cpp_grammar_error.zip

It's a ZIP archive including the preprocessed .ii file, the original C++ source file, and the error spew.

You can read the tracking of the bug so far on the MinGW pages in SourceForge:

https://sourceforge.net/tracker/?func=detail&atid=102435&aid=632454&group_id=2435

Basically, when compiling the file, using this command: 

c:\mingw\bin\g++ -O2 -ftemplate-depth-500 -o 
cpp_grammar.o -c cpp_grammar.ii 

I get an error in a piece of code that looks like this: 

--- 
struct cpp_grammar: grammar<cpp_grammar> { 

... 

template <typename ScannerT> 
struct definition: 
cpp_expressions<ScannerT> 
{ 
... 
template < typename ParserT > 
struct brace_block_functor { 
... 
}; 

template < typename ParserT > 
static 
functor_parser<brace_block_functor<ParserT> > // 
line 2306 
brace_block(ParserT const& parser) { 
return brace_block_functor<ParserT>(parser); 
}; 
... 
}; 
... 
}; 
--- 

The error (sans the "instantiated from" super-spew) says 
this: 

--- 
cpp_grammar.cpp:2306: type/value mismatch at 
argument 1 in template parameter 
list for `template<class FunctorT> struct 
spirit::functor_parser' 
cpp_grammar.cpp:2306: expected a type, got 
`brace_block_functor' 
cpp_grammar.cpp:2306: confused by earlier errors, 
bailing out 
--- 

This is patently wrong. In fact, I have a CygWin with 
GCC 3.0.3 that compiles this program perfectly. 

In tracking this with the MinGW people, they've tried this file with the newest 3.3 compiler, and gotten other errors.
>How-To-Repeat:
Compile the cpp_grammar.ii file from the ZIP file above, using the following command line:

c:\mingw\bin\g++ -O2 -ftemplate-depth-500 -o 
cpp_grammar.o -c cpp_grammar.ii
