--- Begin Message ---Package: bison Version: 2:3.0.4.dfsg-1 Severity: normal Tags: upstream Hi, if an empty rule matches, but calls YYERROR, the parser catches a segmentation fault in the line yyerror_range[1].location = yystack_[yylen - 1].location; inside the error handling, because yylen is 0, (yylen-1) underflows as a 32 bit unsigned value, so the array is accessed at yystack_[4294967295]. On 32 bit system, there is still an invalid access, but this is usually not detected.
