Bug ID: 108553
Summary: GM2 ICEs on mistyped command line options
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
When mistyping -Wreturn-type as -Wereturn-type the compiler ICEs because
we segfault in
#5 0x0000000000c19cfd in gm2_langhook_init_options (decoded_options_count=7,
decoded_options=0x429a190)
at /home/rguenther/src/trunk/gcc/m2/gm2-lang.cc:296
296 fprintf(stderr, "%s : %s\n", opt, (arg ? arg : ""));
(gdb) l
291 /* FALLTHROUGH */
292 default:
293 if (code >= N_OPTS)
294 {
295 // FIXME remove debug.
296 fprintf(stderr, "%s : %s\n", opt, (arg ? arg : ""));
297 break;
298 }
299 /* Do not pass Modula-2 args to the preprocessor, any that we
care
300 about here should already have been handled above. */
(gdb) p opt
$2 = 0x6874616d5f656661 <error: Cannot access memory at address
0x6874616d5f656661>
Note code is OPT_SPECIAL_unknown here.
