Failed assert: unexpected type_builder::visit_unspec (Studio 12.1 CC)

Question

Folks,
I'm trying to port a largish chunk of code from GCC to Studio. The following snippet, whittled down from the
larger code, works fine with g++ but fails with CC 5.10 SunOS_i386 2009/06/03, attempting a 32-bit build on
an Ultra-27, Solaris 10.
Compile command is `CC vectest.cpp'. Error is
>> Assertion: unexpected type_builder::visit_unspec (../lnk/v2mangler.cc, line 1635)
while processing vectest.cpp at line 33.
Code for vectest.cpp is
template <class T> class BCP_vec {
  public:
  typedef T* iterator;
  iterator start;
  iterator finish;
  BCP_vec() {} ;
  iterator begin() { return start; }
  iterator end() { return finish; }
template <class T> void purge_ptr_vector(
       BCP_vec<T*>& pvec,
       typename BCP_vec<T*>::iterator first,
       typename BCP_vec<T*>::iterator last)
  /* Actual code seems to be irrelevant to error */
int main (int argc, char* argv[])
  BCP_vec<double*> vars ;
  purge_ptr_vector(vars,vars.begin(),vars.end());
}Any suggestions for a workaround appreciated.
Thanks,
Lou

It is a known bug. Next version of the compiler (CC 5.11) will compile the code. For CC 5.10, you going to need a patch that I hope will soon be available.
