APAR status
Closed as program error.
Error description
The compiler frontend (xlCentry) produces and internal compiler error when compiling the following test case at -O0. It works fine at -O2 or higher. ===== COMPILE COMMAND: bgxlC -c test.cpp -O0 ===== TEST CASE: $ cat test.cpp struct A{ _Complex double& operator()(int, int); }; void f() { A a; ~a(0, 0); } $ ===== ACTUAL OUTPUT: $ bgxlC -c test.cpp -O0 /opt/ibmcmp/vacpp/bg/12.1/bin/.orig/bgxlC: 1501-230 (S) Internal compiler error; please contact your Service Representative. For more information visit: http://www.ibm.com/support/docview.wss?uid=swg21110810 $ ===== EXPECTED OUTPUT: Should compile clean without an internal compiler error.

Problem summary
USERS AFFECTED: Users of complex operations who use references and optimization are affected by this issue. PROBLEM DESCRIPTION: The complex conjugate operator is not correctly processed when the operand is a C++ reference, which leads to an incorrect optimization that result in a compiler failure during code generation. Minimal TC: _Complex double& foo(); void f() { ~foo(); }
Problem conclusion
The solution is to have the front-end correctly process references in the conjugate operator.
