>Description:
If a static const member of type pointer to member is initialized in class, and the initializer is a template argument, gcc-3.2 exits with a segmentation fault.
The full compiler output is as follows:
c++ -Wall -c -o nocompile.o nocompile.ii
gccbug.1.cpp: In instantiation of `B<&A::dummy>':
gccbug.1.cpp:21: instantiated from here
gccbug.1.cpp:11: internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
Gcc-2.95.3 compiles such a construct fine.
>How-To-Repeat:
compiling of the attached preprocessor output (c++ -Wall -c nocompile.ii).
>Fix:
A non in-class initialization is accepted.
I.e. :
-------------------------------
class A;
template<int A::* P>
class B
{
public:
static int A::* const p;
};
template<int A::* P>
int A::* const B<P>::p = P;
class A
{
public:
int dummy;
B<&A::dummy> d;
};
--------------------------------
compiles just fine.
