[Bug c++/13618] New: 'internal compiler error: in c_expand_expr, at c-common.c' when printing a compile error

[youkai at earthlink dot net]

When compiling a small program involving a fair amount of template processing, 
gcc aborts with 'internal compiler error' when trying to print out a 
programming error:

CacheTemplate.cpp: In member function `Value& Cache<Key, Value, MissHandler, 
   ReplacementPolicy>::get(const Key&) [with Key = int, Value = char, 
   MissHandler = CharMaker, ReplacementPolicy = TestReplacementPolicy]':
test.cpp:36:   instantiated from here
CacheTemplate.cpp:12: internal compiler error: in c_expand_expr, at c-common.c:
   4341
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I will include the preprocessed source, as soon as I can figure out where to 
upload it.

[Bug c++/13618] 'internal compiler error: in c_expand_expr, at c-common.c' when printing a compile error

The code is illegal, because you have something like this: 
   EntryType(_missHandler(1),  
             ReplacementPolicy::EntryMetadata).first; 
where the second argument to EntryType is here a type, but should be 
a value. Nevertheless, this is of course an error in gcc, and I'm trying 
to reduce it.

Actually, there was also a "typename" missing. Well, be that as it 
may, here's a small snippet: 
--------------------- 
struct S { 
    S(int, int); 
}; 
 
struct TestT 
{ 
    typedef int I; 
}; 
 
template <typename T> 
void get() 
{ 
  S s(1, T::I); 
} 
 
template void get<TestT> (); 
---------------------------- 
 
This crashed everything between 2.95 and present 3.3.x with 
g/x> /home/bangerth/bin/gcc-3.3.3-pre/bin/c++ -c x.cc 
x.cc: In function `void get() [with T = TestT]': 
x.cc:16:   instantiated from here 
x.cc:13: internal compiler error: in c_expand_expr, at c-common.c:4341

with preprocessed source if appropriate.

It's fixed on mainline, though, so no action requires anymore.
