Ok i think it isn't the sollution to put the match into a var ($1)
but trowing a addslashes at the found match will be a good start:

to make it easy for you :)
i think it should be change somewhere in function preg_do_eval
(etx/pcre/php_pcre.c)
558 + 559:
         match = subject + offsets[backref<<1];
         match_len = offsets[(backref<<1)+1] - offsets[backref<<1];

someone said to me to add this after thos statements:
       match = php_addslashes(match,0, &match_len,0); match_len--;

the problem of the eval is fixed then but the founded match is to long when
you get it in the function.

I'm not a c programmer, so if someone could fix this please
and send me a diff or even better puts it in the cvs my day will be good
(and i can continue to work, boss also happy :)

Greetz,

Wico
