[BZ] bug in the g++ 4.7.2-5 compiler that is in the RH DTS v1.1

Issue

• If compiled on RHEL 6 using the native compiler, it compiles fine:

[mymachine:346] c++ -v
gcc version 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) 
[mymachine:347] /usr/bin/c++ funcptrtmplarg.C -o it.o

• If compiled on RHEL 6 using a gcc 4.8.1 that I just built, it compiles fine:

[mymachine:348]
/wv/cst5/cst_projects/evelyn/gcc-4.8.1/install/H-x86_64-rhel6-linux-gnu/bin/c++
funcptrtmplarg.C -o it.o

• But if you compile on RHEL 6 using the RH DTS it generates a bogus error:

[mymachine:349] /opt/rh/devtoolset-1.1/root/usr/bin/c++ funcptrtmplarg.C -o it.o
funcptrtmplarg.C: In instantiation of ‘class A<int, double>’:
funcptrtmplarg.C:86:18:   required from here
funcptrtmplarg.C:79:40: error: could not convert template argument ‘&A<int,
double>::increment’ to ‘void (A<int, double>::*)(A<int, double>::B&)’
funcptrtmplarg.C:80:40: error: could not convert template argument ‘&A<int,
double>::decrement’ to ‘void (A<int, double>::*)(A<int, double>::B&)’
