[TRE-general] Why Retest fail on these?

[OcTweak]

Hi,

Using tre version 0.7.5:

I added the following lines to retest.c.

Could someone explain me why these tests fail?
 
test_comp("[\\x0D\\x0A]\\x41", REG_EXTENDED, 0);
test_exec("\nABC4", 0, REG_OK, 0, 2, END);
test_exec("\rABC5", 0, REG_OK, 0, 2, END);


Thanks in advance

Anderson
