Hi,
Today I was writing some new tests for tidy, but they aren't working because
of some problem in the engine or the streams stuff that leads to memory
corruption.
The test is ext/tidy/tests/020.phpt.
Attached is a nice valgrind log :)

Strict Standards: date(): It is not safe to rely on the system's timezone
settings. Please use the date.timezone setting, the TZ environment variable or
the date_default_timezone_set() function. In case you used any of those methods
and you are still getting this warning, you most likely misspelled the timezone
identifier. We selected 'Europe/Paris' for 'WEST/1.0/DST' instead in
