Yes I did. I got two problems with the current code:

in procedure
int xdebug_dbgp_init(xdebug_con *context, int mode)

    send_message(context, response TSRMLS_CC);

I think XG(remote_log_file) = NULL; is missing in front of this as
send_message is using remote_log_file. Anyway I got the init part to
crash already with the latest code without that fix.

2) if I am for example in main thread (not in an object method) and ask
for variable $this->somethingthatdoesnotexist then I get to _xdebug_do_eval.

res = zend_eval_string(eval_string, ret_zval, "xdebug eval" TSRMLS_CC);

will crash and eval_string does have that $this... so something in Zend
is crashing.

I did an idiotic quick hack

    if (*eval_string && strstr(eval_string, "$this->") == 0)
      res = zend_eval_string(eval_string, ret_zval, "xdebug eval"
      res = 0;

and got rid of the problem.

Thank you and please let me know if I should have posted this text to
somewhere else as it is quite code specific.
