Per https://gcc.gnu.org/bugs/ 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). Obviously, if you can trim the input it's good, but it doesn't have to be a minimal reproducer. regards, tom lane
