[Bug preprocessor/22042] New: stringification BUG

[s__nakayama at infoseek dot jp]

// test code
#define S(X) S2(X)
#define S2(X) #X
#define TAB "	" /* 0x09 */

S(S(TAB))


// gcc -E -P OUTPUT

"\"\\\"\\011\\\"\""

// expected result

"\"\\\"	\\\"\""


GCC # preprocessing operator converts the non-printable characters to octal.
But this behavior is non standard.
