Wrong result only if another rule is present #57
Description
The following program produces the wrong result
3: \baaa
If the first rule [<]... is removed, the correct result is produced:
8:
This could be reproduced with re2c 0.13.7.5 and 0.14.1. Versions 0.13.5 and 0.13.6 work fine.
(This is a reduced testcase. The problem was discovered in a more complicated scanner in libcmark.)
#include <stdio.h>
int scan(const char *p)
{
#define YYCTYPE char
const char *YYCURSOR = p;
const char *YYMARKER;
/*!re2c
re2c:yyfill:enable = 0;
reg_char = [a];
escaped_char = [\\][b];
[<] ([x] | escaped_char | [y])* [>] { return YYCURSOR - p; }
(reg_char | escaped_char)* { return YYCURSOR - p; }
. { return 0; }
*/
}
int main()
{
const char *str = "aaa\\baaa";
int res = scan(str);
printf("%d: %s\n", res, str + res);
return 0;
