Bug #: 54927
Summary: internal compiler error: in tsubst_copy, at
cp/pt.c:12349
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ca...@cs.stanford.edu
When compiling this program without options:
template<class T> class A {void F(){sizeof(double);}};
template class A<int>;
The compilation should succeed, but I get the following output:
prog.cpp: In instantiation of ‘void A<T>::F() [with T = int]’:
prog.cpp:2:16: required from here
prog.cpp:1:43: internal compiler error: in tsubst_copy, at cp/pt.c:12349
template<class T> class A {void F(){sizeof(double);}};
