[Tinycc-devel] report a bug

[837806295]

hello, report a bug, my English is not good, hope you understand.

bug info

file: tccpp.c

function: parse_escape_string

line: 2010

------------------------------------------------------

do {

c = *p;

if (c >= 'a' && c <= 'f')

c = c - 'a' + 10;

else if (c >= 'A' && c <= 'F')

c = c - 'A' + 10;

else if (isnum(c))

c = c - '0';

----> else if (i > 0)

expect("more hex digits in universal-character-name");

else

goto add_hex_or_ucn;

n = n * 16 + c;

p++;

} while (--i);

it should be

else if (i >= 0)

------------------------------------------------------

the following code can show the problem:

#include <stdio.h>

int main(int argc, const char **argv)

{

int x = '\x';

printf("%d\n", x);

return 0;

}

------------------------------------------------------

in gcc, it should not be compiled??report error like:

main.c: In function ??main??:

main.c:6:13: error: \x used with no following hex digits

int x = '\x';

------------------------------------------------------

in tcc, it can be compiled. no error!
