I do, my plugin can handle this kind of STL type imbrication.

3.5.1

indeed, it seems there is a problem with KDevelop

If you try a very simple project like that :

#include <vector>

int main(int, char **)
{
	std::vector<int> v;
	v.push_back(1);
	v.push_back(2);
	v.push_back(3);
	v.push_back(4);
	v[2]=5;
	*(v.begin()) = 6;
	return 0;
}

	in KDevelop, place a breakpoint on the "v.push_back(2);" line, add a
watch expression to 'v'.

	Expand local and watch views of 'v' variable. Then step line by line,
and you'll see that 'watch' part is correctly updated, whereas 'local'
part is not.

	Could it be fixed by something in my GDB patch, or is it a KDevelop
problem, ie does KDevelop assumes that an array never changes its size ?
