Bogdan,
In my testing I found that this error still occurs in revision 6981, but only if debug=4 or higher.

382 LM_DBG("references:%d , max:%d\n",namecount,repl_comp->max_pmatch);

Hi Sven,
I made a fix on SVN trunk (see revision 6948) - please check it out.
After more tests, I will move it to 1.6 branch too.

Bogdan
