Qt Gdb is crashing my application with exit code 1

When I try debugging my Qt C++ application from within Qt Creator, it crashes consistently with the following error message:

**An unhandled win32 exception in gdb.exe**

However, when I try launching the same binary by double clicking it, it runs just fine. Also, I can also run my binary on gdb from the command line like this

C:\Users\CoolCast>c:\MinGW4.4\bin\gdb.exe C:\QuiKast\git_apps_0_1\Server\MediaSt
reamServer-build-Desktop-Debug\debug\CoolCast.exe
GNU gdb 6.8

(gdb) run

... and so on.

My environment and program versions are:

Windows 7
Qt SDK 4.8.4
MinGw 4.4
GDB auto-detected under Mingw and set to C:\Mingw4.4\bin\gdb.exe

For me switching to the auto-detected debugger worked. I was using c:\qtx64\mingw64\bin\g++.exe for my debugger and I got the same or a similar error: the gdb process terminated unexpectedly (code 1). Then I went into my MinGW 64-bit kit (Tools->Options->Build & Run->Kits) and clicked the Auto-detect button next to the Debugger field. This switched my debugger to c:\qtx64\mingw64\bin\gdb.exe. Rebuilt my project (which may or may not have been necessary) and started the debugger from inside Qt Creator (Qt Creator 2.7.0 ; Based on Qt 4.8.4 (32 bit)) and bada bing it worked.
