Creating a C++ project will cause eclipse to lockup depending on the contents of your autorun.bat file.  I use autorun.bat so that I can have a few aliases in my command prompt.  Recently I added 'C:' as the first line so that new terminals would start pointed at my C drive.  After doing this I was not able to work with C\C++ projects.  I found that the following command is being issued when creating a C project or converting to a C project:

cmd /c set PROCESSOR_ARCHITECTURE

Having the 'C:' as the first command in the .bat file caused eclipse to hang on the above call and never come back.  I was able to fix this by adding '@echo off' at the beginning of my .bat file.  There should be some way to put a timeout on that system call.

It does not crash, it just sits waiting for that call to return.

Reproducible: Always

Steps to Reproduce:
1.  Create an autorun.bat file
2.  Set the following registry with the path to your autorun.bat file:
HKEY_CURRENT_USER\Software\Microsoft\Command Processor
2.  Verify that it is being read (maybe add a doskey command or something)
3.  Add a line at the beginning of the file that will change drives.
Example:
C:
4.  Start eclipse and try to create a new C/C++ project

I guess we should run 

  cmd /c /d set PROCESSOR_ARCHITECTURE

to avoid the auto run commands.

or rather

  cmd /d /c set PROCESSOR_ARCHITECTURE
