Summary: internal compiler error: output_operand: invalid expression as operand Product: gcc Version: 4.4.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: tom...@gmail.com When asked to compile the following C++ source, gcc gives the message "internal compiler error: output_operand: invalid expression as operand" The program in full (it's only one line long) is: char cc[300]; int& c = *(int*)(int(&cc[150]) & ~15); Invoke gcc with no command line arguments, e.g. gcc sample.cc ( although I saw the same thing on x86_64 when compiling with -m32 ) g++ -v output: Using built-in specs.
