[lazarus] Lazarus ansistring AV?

[Micha Nelissen]

Hi,

Currently, lazarus crashes continually on my box. Backtrace:

#0  $006b2ed9 in SYSWIN32$$_ANSISTR_DECR_REF$POINTER ()
#1  $006b2f88 in SYSWIN32$$_ANSISTR_ASSIGN$POINTER$POINTER ()

Is this a bug in the ansistring functions? Sometimes it starts bugging 
me, then mysteriously disappears again. But now it doesn't disappear :(. 
Any hints, please?

Thanks,

Micha.
