Launching the debugger in mode "gdb" hangs forever

System information:
-OS: Windows 10
-VS code version: 1.32.3
-Extension: C/C++, version 0.22.1
-Compiler/debugger version: MinGW.org GCC-8.2.0-3

Bug description:
When launching the debugger, configured in mode "gdb", the blue bar is loading forever and nothing happens. I already tried to enable logging but nothing is output to the VS code debug console. However when setting externalConsole to false, the following line is printed in the integrated terminal:

env "c:\Users\brunn\.vscode\extensions\ms-vscode.cpptools-0.22.1\debugAdapters\bin\WindowsDebugLauncher.exe" --stdin=Microsoft-MIEngine-In-fyz0vlaa.gej --stdout=Microsoft-MIEngine-Out-0aiqcb4f.wbn --stderr=Microsoft-MIEngine-Error-gvbsagt3.yu1 --pid=Microsoft-MIEngine-Pid-aqbc4pf3.3dh --dbgExe=C:/Data/Programmes/MinGW/bin/gdb.exe --interpreter=mi

However, this command never terminates and it seems like something goes wrong during the execution of that command.
