Description Kim van der Riet CLA 2012-01-05 07:20:39 EST 
Build Identifier: 201107251854

Code which makes use of boost pointer containers and which rely on the iterator auto-indirection feature of these containers are marked as bugs/errors. However, the code is correct and compiles without problems.

I have only tested iterator auto-indirection; other uses of these containers may also show such behavior.

A simple reproducer is attached.

Reproducible: Always

Steps to Reproduce:
See attached reproducer.

Create a C++ project with this file as the source. See comments in source for further details.

This file does not do anything useful; it does compile successfully using g++.
Comment 2 Markus Schorn CLA 2012-01-05 08:47:24 EST 
what version of CDT are you using?
Comment 3 Kim van der Riet CLA 2012-01-05 09:04:56 EST 
Sorry, I thought the build id was sufficient. I am not an Eclipse insider, I find the different version numbers for all the CDT bits confusing, so I don't know which one you are looking for... 

I assume this is the one:
Eclipse C/C++ Development Tools  8.0.0.201106081058

but in case it is not, here are the other CDT bits listed:

C/C++ Remote Debug Launcher  6.0.0.201106081058
Eclipse GCC Cross Compiler Support 1.0.0.201106081058
Eclipse CDT P2 Customizations for SDK installation 1.0.0.201106081058
CDT Debugger Services Framework (DSF) Examples  2.1.0.201106081058
Eclipse C/C++ Development Tools  8.0.0.201106081058
Eclipse C/C++ Development Tools Utilities 5.1.0.201106081058
Eclipse GDB Hardware Debugging 7.0.0.201106081058
Eclipse Debugger for C/C++ 2.0.0.201106081058
GDB Common  7.0.0.201106081058
Comment 4 Markus Schorn CLA 2012-01-09 02:54:00 EST 
Reproduced the problem (boost 1.46.1 and  CDT 8.0.1) and verified that it works on the master branch.

I suspect the bug id got mixed up when marking the bug as a duplicate.

Thanks, I mistyped the bug id.
