------- Comment #1 from pinskia at gcc dot gnu dot org 2007-03-19 09:26 -------
It seems like this can be made into valid code and still ICE.
The valid code is:
template<class T1> struct S1 {
template<bool T2> struct S2;
template<template<bool> class T3> struct S3 {
template<typename T4=S3<S2> > struct S4 {};
struct S5 : S4<> {
};
};
};
-----
Note if I change how S5 is declared using a specific template argument instead
of <>, the crash goes away in that the follow compiles just fine:
template<class T1> struct S1 {
template<bool T2> struct S2;
template<template<bool> class T3> struct S3 {
template<typename T4=S3<S2> > struct S4 {};
struct S5 : S4<S3<S2> > {
};
};
};

Btw, the bug appeared in GCC 4.0.2.
The code compiles with GCC 4.0.1 or earlier.

Fixed on the trunk by Steve Ellcey's patch for PR38357.
Steve, would you mind backporting the patch to the 4.3 branch as it fixes an
ice-on-valid-code regression there?
