The following code snippet crashes GCC 4.1.1 and 4.2.0 20060820 (experimental):
------
template<typename T>
void f(T& r)
{
T a = r;
}
void g()
{
f(g);
}
------
Saving the code in a file a.cc and executing "c++ -c a.cc" produces:
------
a.cc: In function 'void f(T&) [with T = void ()()]':
a.cc:9: instantiated from here
a.cc:4: internal compiler error: in digest_init, at cp/typeck2.c:709
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
------
The above output is produced by GCC 4.1.1. With the mentioned GCC CVS snapshot
the linenumber where the ICE is reported changes to cp/typeck2.c:718.
This bug might be related to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27807.
GCC 3.4.6 does not ICE, and rejects the code with a diagnostic, which is
correct behaviour as far as I know.
