Bug #: 14030
Summary: No children returned for unitialized pointer to class
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: mi
AssignedTo: unassigned@sourceware.org
ReportedBy: jens.elmenthaler@me.com
Classification: Unclassified
I have the following set of source/header files:
// ClassUnderTest.hpp
class ClassUnderTest {
public:
ClassUnderTest();
virtual ~ClassUnderTest();
bool mTrue;
int mFifteen;
};
// ClassUnderTest.cpp
#include "ClassUnderTest.hpp"
ClassUnderTest::ClassUnderTest()
: mTrue(true),
mFifteen(15)
{
}
ClassUnderTest::~ClassUnderTest()
{
}
// client.cpp
void client()
{
ClassUnderTest *pCUT= new ClassUnderTest; // breakpoint here -> 0 children,
stepping to next line does not help
delete pCUT; // breakpoint here -> OK
pCUT = 0;
}
If I set a breakpoint at the first line in client(), pCUT has no children, and
also stepping over this line will not yield the children.
If I set the breakpoint to the second line, i.e. pCUT is initialized already, I
get the expected children.
It seems to be relevant that client() and the implementation of
ClassUnderTest's methods are in separate source files. If I implement the
methods in ClassUnderTest.hpp, or move client() into ClassUnderTest.cpp,
everything works properly again.
I use a gcc 4.1.2.
This seems to be related to the changes for bug 376901, which now rely on the
type information of the value instead of target type information calculated on
the fly (get_target_type()).
