Summary: Problems with frame stack handling
Product: kdevelop
Version: SVN
Platform: Compiled Sources
OS/Version: Linux
Status: NEW
Severity: major
Priority: NOR
Component: CPP Debugger
AssignedTo: kdevelop-bugs kdevelop org
ReportedBy: amantia kde org
The debugger fails to display the content QStringList (Qt3) correctly.
The code is something like this:
PluginController::getInstance()->unloadPlugins( m_info->m_ignoreParts );
m_info->m_ignoreParts is the QStringList, and has one element (node).
If I watch the variable, it shows:
There is no member or method named QValueList<QString>. for the "data" field of
the nodes,
but it correctly show that the list has 1 nodes.
Furthermore in the unlodPlugins we have:
void PluginController::unloadPlugins( QStringList const & unloadParts )
{
QStringList::ConstIterator it = unloadParts.begin();
while ( it != unloadParts.end() )
{
...
}
unloadParts should be the same as m_info->m_ignoreParts. Well, at this stage
the debugger doesn't even
show *any* value for the "nodes" entry (should be 1), and of course the above
problem is present here as well.
The above information is from bug #138040 and repeated here to give background
about the frame stack bug described below.
If I want to go back to inspect m_info->m_ignoreParts again, I click on the #1
frame in the frame stack. It
goes back to the correct line (the above one), gives me some errors:
Can't take address of "this" which isn't an lvalue.
Can't take address of "this" which isn't an lvalue.
Address requested for identifier "part" which is in register $rbp
Variable object not found
No symbol "m_info" in current context.
Variable object not found
There is no member or method named QValueList.
There is no member or method named QValueList.
and I end with a disabled m_info->m_ignoreParts under Watch. I *cannot* remove
it, but
I can add again the same m_info->m_ignoreParts under Watch, ending with two
entries.
Doing so more errors appear:
No symbol "m_info" in current context.
mi_cmd_var_create: unable to create variable object
Variable object not found
Variable object not found
No symbol "m_info" in current context
Variable object not found
Variable object not found
No symbol "m_info" in current context.
The new entry is added, but I still cannot inspect the variable's value.
The double error messages might come because I had two entries for
m_info->m_ignoreParts.
