Hi!
I faced a several problems while trying to debug my code in C::B 16.01 (there was no such problems in 15.12 and pre-16.01 nightlies). I`m not sure if all this problems are C::B related, so I post it here instead of bugtarcker.
My system:
C::B: Release 16.01 rev 10702, windows unicode 32-bit.
OS: Windwos 7 Pro (x64)
GCC: tdm64-1 5.1.0
GDB: GNU gdb (GDB) 7.9.1 (x64)
Problem #1:
While debugging multi-threaded application, when switching stack frame "Threads" window suddenly shows call stack information, and "call stack" window becomes empty. Click on such "threads" actually do switches threads and updates call stack. I mean, if I have 5 threads, I still could switch it clicking on first 5 lines of text (call stack) and other lines do nothing. Just like Threads window works fine but it contents displayed incorrectly.
Sometimes repeated switch of stack frame restores threads list. But, on the other hand, rarely some actions makes "Watches" window show call stack contents as well.
From the debugger log it looks like C::B asks GDB for threads list before previous command output completes. Here is partial log:

Problem #2:
When console process is running, it could not be stopped nor paused. If I run it free (no debugger) - "Abort" button just hides its window, but all processes continue to run in background (conhost.exe, cb_console_runner.exe and test.exe).
It I run it under debugger, both "Pause" and "Stop" buttons does nothing. Only message "Trying to interrupt process with pid: 1596; child pid: 1596 gdb pid: 3112" appears. Process tree looks like that:
csrss.exe
conhost.exe [2976]
conhost.exe [3156]
codeblocks.exe
gdb.exe [3112]
gdb.exe [4872]
test.exe [1596]
Problem #3:
After debugee stopped on breakpoint and then terminated using stop button, if I run another debug session, it starts with the "Call stack" filled with information from the point it was terminated last time. Note that I use "Do *not* run debugee" setting enabled. After I run it to the some breakpoint in main() call stack refreshed with correct actual data.
Also, may be related: after I close workspace and open another one, "Build log" and "Build messages" not cleared and still contains old logs.
Is all this problems could be a C::B bugs or could be solved somehow? Thanks for your time and help!
