I can't reproduce:

$ ~/php/php5.3-t/bin/php -r "echo nl2br(new mysqli);"

Warning: nl2br() expects parameter 1 to be string, object given in Command line code on line 1

I also find no problem in nl2br (all pretty standard). Can you give more details?

Seems that the segfault is caused by the object itself, I will post more details as soon as i know something. Sorry for the misleading description.

I'm closing as bogus. If you find the problem, please submit a new bug report.

Than you.
