Testcase that still ICEs on the trunk even when optimizing: int main (int argc, char **argv) { int size = 10; typedef struct { char val[size]; } block; block b; block __attribute__((noinline)) retframe_block () { return *(block *) &b; } b=retframe_block (); return 0; } as alternative to rejecting this case we can lower returning variable-size types during un-nesting to explicit passing of a return slot and using memcpy, making the nested function return nothing. -- Configure bugmail: http://gcc.gnu.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. -- To UNSUBSCRIBE, email to debian-gcc-requ...@lists.debian.org with a subject of "unsubscribe".
