I'm using eclipse for c/c++ and MingGW to make c++ project, which has multi-thread program. when I was debugging it with gdb, and met API like "CreateThread", it would show the following info and cannot trace step by step.

[New Thread 6684.0x2378]
[New Thread 6684.0x1df8]
warning: SuspendThread failed. (winerr 2)
Quit (expect signal SIGINT when the program is resumed)
Quitting: PC register is not available

it seems that I create thread B in thread A, after switch to B, program cannot back to A again, while I fail to make breakpoints in B.

eclipse-cpp-juno-win32-x86_64
mingw32
gdb 7.6.1

Would you help me to solve the problem? thanks for your interest.
Regards,
Chuan

I think maybe there exists bugs when GDB debugs multi-thread program with environment of eclipse+CDT.

If it is, I will commit this problem to eclipse.
