Bug ID: 48342
Summary: LLDB crashes when inspecting an object created using
ni::type_hierarchy
Product: lldb
Version: unspecified
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: hbu...@fender.com
CC: jdevliegh...@apple.com, llvm-b...@lists.llvm.org
When using the Native Instruments open source library matchine, the
ni::type_hierarchy objects crash the LLDB RPC Server when inspected using Xcode
12.
Here is the issue filed against the matchine library:
https://github.com/NativeInstruments/matchine/issues/1
Here is an example that crashes LLDB. It requires the matchine library which
has a dependency on boost.
```
#include <iostream>
#include <ni/type_hierarchy.h>
struct EventBase {
EventBase() = default;
virtual ~EventBase() = default;
};
using Event = ni::type_hierarchy::from_base<EventBase>;
NI_SUB_TYPE(struct TestEvent, Event)
{
int value = 0;
TestEvent(int value_)
: value( value_ )
{
}
};
int main(int argc, const char * argv[]) {
TestEvent testEvent(100);
// insert breakpoint here to inspect testEvent
// inpecting testEvent will crash LLDB
TestEvent testEvent2(200);
return 0;
}
```
