Description galeazzi CLA 2010-11-30 11:29:51 EST 
Build Identifier: 20100917-0705

I currently use mingw with GDB 7.2 (but the same thing happens with 7.1) and gcc 4.5.0
The attached sources make up a simple multithread application which emulates a more complex one, but they both have the same behaviour.
If I run the application without a breakpoint everything works well, but as I try to add a brekpoint in a line exectuted by a thread, the debugger locks in the following state:
[Switching to Thread ....]
So I can do nothing but terminate the application. I also tried to comunicate with gdb in the console but it doesn't respond to any command.
I debugged the same code with Netbeans/MinGW and everything works fine.
Let me know if you need any other information

Reproducible: Always

Steps to Reproduce:
1. Compile the attached code
2. Add a breakpoint to PICalculator::calculate() (but you can also choose other lines)
3. Debug the application

1) Please attach a Java backtrace when Eclipse is deadlocked:
  http://wiki.eclipse.org/How_to_report_a_deadlock
2) Please provide the version of CDT used in your Eclipse (look in Help > About > Installation Details).
