Summary: xdebug uses enormous amounts of memory when tracing or profiling long running scripts.
Description:
While debugging an export script which exports some hundred megabytes of
data to a csv file I noticed that the apache consumed increasing amounts
of memory.

,----[ ps uax ]---
| USER PID %CPU %MEM VSZ RSS TTY STAT START TIME
COMMAND
| www-data 9488 4.6 68.5 1052576 709888 ? S 05:12 3:05
/usr/sbin/apache2 -k start
`----

I discoverd with lsof that this apache process was the one which had php
running to export the data. PHP has a configured memory limit of 64MB and
also they're no data structures in the script which could hold such
enormous amount of data.

Is this a known problem?

No, not known problems... perhaps you can come up with a short reproducing
script?
