--- Comment #6 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- "What we need Please include all of the following items, the first three of which can be obtained from the output of gcc -v: the exact version of GCC; the system type; the options given when GCC was configured/built; the complete command line that triggers the bug; the compiler output (error messages, warnings, etc.); and the preprocessed file (*.i*) that triggers the bug, generated by adding -save-temps to the complete compilation command, or, in the case of a bug report for the GNAT front end, a complete set of source files (see below)."
