System: Linux linux 2.4.19 #1 Sat Aug 3 13:08:17 CEST 2002 i686 unknown
Architecture: i686
<machine, os, target, libraries (multiple lines)>
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu

>Description:
If a static const member of type pointer to member is initialized in cla
ss, and the initializer is a template argument, gcc-3.2 exits with a segmentatio
n 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.
(This report is just like PR8152, which somehow missed the file attachment. I am sorry for that.)
>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.
