RE: [cdt-dev] CDT 2.1 RC5 Now Available for Testing: no access to global variables 
Hallo,

I made a first test to the CDT - RC5 version. Good work to get rid of so
many bugs. 

From my private bug list, the Xlinker issue is gone. Although it seems that
the string with comma ("Xlinker, <xxx>") is used during the first start of
CDT after installation. I changed some preference options and suddenly the
correct string "Xlinker <xxx>" was used (any explanation for this?).

However I recognized a problem to display global variables. When you debug
an application you can display values of variables on different way: 

(1) you browse through the source code. When your mouse hits a (local or
global) variable, the value of this variable is shown. This works well.
(2) you can use the variable window to display the local variables of a
procedure (works also). In addition, you can add global variables to this
view. This doesn't seem to work. The exception shown below happens and no
global variable is added to this view.

I did not test this before. I had a discussion with a collegue. It looks
like way (2) works with CDT 2.0.2 (she is using this version). The problem
may be 2.1 related.

Regards. Manfred.
