[ROOT] Severe problem with struct containing Boolean variable

Dear Rooters

I am running root 3.05/02 on MacOS X 10.1.2 and get a strange
error when a struct contains a boolean variable.
The enclosed macro1.C runs without problems.
However, in macro2.C I changed fVar1 from Int_t to Bool_t, and
thus get the following error:

root [0] .x macro1.C
fTxt2 = aaa
fTxt2 = bbb
fTxt2 = ccc
root [1] .x macro2.C
Error: Illegal pointer operation (letvalue) FILE:macro2.C LINE:12
Error: Illegal pointer operation (letvalue) FILE:macro2.C LINE:13
Error: Illegal pointer operation (letvalue) FILE:macro2.C LINE:14
Error: Illegal pointer operation (letvalue) FILE:macro2.C LINE:15
*** Interpreter error recovered ***
root [2] .x macro3.C
Error: Illegal pointer operation (letvalue) FILE:macro3.C LINE:15
Error: Illegal pointer operation (letvalue) FILE:macro3.C LINE:16
Error: Illegal pointer operation (letvalue) FILE:macro3.C LINE:17
Error: Illegal pointer operation (letvalue) FILE:macro3.C LINE:18
Error: Illegal pointer operation (letvalue) FILE:macro3.C LINE:19
*** Interpreter error recovered ***
root [3]

My real problem is shown in macro3.C which results in the same
error!

Could this be a CINT problem with MacOS X?
How can this problem be solved?

Best regards
Christian
