Subject: [cdt-dev] StackOverflowError in the DOM Parser


Dear CDT Developers,

I was testing the CDT Parser using a plugin that traverses the AST and
resolves Bindings for Function Calls. I tried to create the AST and
resolve Bindings of called functions for the Mozilla 1.7 source.
No includes where added to the CProject.  I just opened a new C++
Standard Make Project and added the mozilla sources. Then I ran my
visitor on the project (without compiling the project before).

A StackOverflow occured when traversing the file
./mozilla-1.7/content/xul/templates/src/nsXULTemplateBuilder.cpp at line
1136. At this line there is a function call to the function
ParseAttribute:

ParseAttribute(aAttributeValue, IsVarInSet, nsnull, &closure);

Maybe this is a rare case, but I think the parser should not cause an
Error, no matter what the input is.
I spend some time on debugging but did not really succeed in finding the
actual cause. I think the whole thing goes up when the parameter
IsVarInSet (a function pointer) is resolved. I also found that CPPScope
contains two IASTNames with the 

for ParseAttribute - maybe there is a problem.
Unfortunately I do not have the resources now to really dig into the CDT
code and resolve the problem, but maybe somebody that knows the code in
and out can find a quick solution.

Please find the error report attached.
To reproduce the example, I added a small visitor and the mozilla source
files that caused the error (to reproduce the error it is sufficient to
add only the files nsXULTemplateBuilder.cpp and nsXULTemplateBuilder.h)

Please let me know if this is a known issue and maybe you can provide a
workaround, otherwise I can report the bug in the bugzilla.


Regards,

Johannes
