temporary() problem [message #86024]

Hi,

I'm not sure I understand why the variable 'a' below gets undefined after calling a procedure using temporary():

IDL> a='a, b, c'
IDL> help, a
A STRING = 'a, b, c'
IDL> .run "test.pro"
% Compiled module: TEST.
IDL> test, a
IDL> help, a
A UNDEFINED = <Undefined>

The contents of test.pro:

PRO TEST, str
ostr=strsplit(temporary(str), ', ', /extract)
END

Why is temporary() messing with the top level environment?

Seb
