Confirmed.
> g++ -S t.C
t.C: In function 'int main(int, char**)':
t.C:8:26: error: cast from 'const char*' to 'int' loses precision
[-fpermissive]
t.C:8:31: error: '(int)((long int)"123")' is not a constant expression
t.C:8:31: note: in template argument for type 'int'
> g++ -S t.C -m32
t.C: In function 'int main(int, char**)':
t.C:8:31: internal compiler error: in convert_nontype_argument, at cp/pt.c:5408
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
On trunk:
> g++ -S t.C -m32 -B /abuild/rguenther/trunk-g/gcc
t.C: In function 'int main(int, char**)':
t.C:8:31: error: conversion from pointer type 'const char (*)[4]' to arithmetic
type 'int' in a constant-expression
t.C:8:31: note: in template argument for type 'int'
so it's invalid source, fixed on trunk. 4.5 says
g++ -S t.C -m32
t.C: In function 'int main(int, char**)':
t.C:8:31: error: '(int)"123"' is not a valid template argument for type 'int'
because it is a non-constant expression
