The loop is mainly in function "void ParserThread::DoParse()", if you would like to enable the TRACE macro, it is setting:
#define CC_PARSERTHREAD_DEBUG_OUTPUT 1
But it will log MANY messages.
I think you can try to disable all the four options in, Editor->Code Completion->C/C++ Parser, so that only the files in your cbp file will be parsed.
If you have narrowed down the endless loop in one file, then you can try the cc_test project, and put the code snippet in "test.h", this will find the bug quickly.
Also, the log and debug log message should be redirected to files (I think C::B has such start up options)
FYI: they are options below:
--log-to-file --debug-log-to-file
For each open file, this stalls CB for about 7 seconds.
An erroneously specified file, such as "..\..\..\..\iccv8cortex\include\CMSIS\core_cm3.h" where iccv8cortex is actually located at c:\iccv8cortex will cause the top level path to be set to C:\

To recreate the CC root scan quirk:
Download:
https://dl.dropboxusercontent.com/u/46870262/iccv8cortexCCRootScan.7z
Unpack and place the folder iccv8cortex at the root of drive c:\
Load the examples project:
c:\iccv8cortex\examples.cortex\examples.workspace
Alt-G to load tasks.c
Alt-G to load croutine.c
close workspace, then reload it.
CC will scan all of the hard disk starting at root C:\
Thanks for the example projects. But I can't reproduce this bug.
What is your CC setting? One parser per project(in this case the maximal allowed parser number is?) or one parser for the whole workspace?
Besides that, how do you know "CC scan the root of C:\"? Can you put a breakpoint in the line below (in plugins\codecompletion\systemheadersthread.cpp):
HeaderDirTraverser traverser(this, m_SystemHeadersThreadCS, m_SystemHeadersMap, dirs[i]);
dir.Traverse(traverser, wxEmptyString, wxDIR_FILES | wxDIR_DIRS);
Then you can see what is the actual dir the Traverser's working one. If it contains a C:\, then the traverser will scan all the files/sub-folders of the C:\.
What I find if I start C::B with debug-log is:
Traversing 'C:\iccv8cortex\examples.cortex\FreeRTOS\Source' for: tasks.*
Traversing ' - C:\' for: tasks.*
Found 1 files:
- C:\iccv8cortex\examples.cortex\FreeRTOS\Source\tasks.c
But even renaming the folder, so that it starts with "Z" the file is found nearly immediately (without much hdd-activity).
Be sure that View: is set to "Current File's symbols" and that task.c and croutine.c is loaded in the editor.
"Use one parser per project" is set.
Yes, I've set the trap and GetTopLevelPath() hands back "C:\" to CC.

You have he same file twice in it (with different relative paths):
<Unit filename="..\..\..\..\iccv8cortex\include\CMSIS\core_cm3.h" />
<Unit filename="..\..\..\include\CMSIS\core_cm3.h" />
The issue can simply be fixed by explicitely saving the projectfile, closing and reopening it.
Nevertheless the calculating of the common toplevel path should work correctly in this case also in my opinion.
