Hi
I have a Class that instantiates a MallocMessageBuilder and initializes its
root to a custom struct. I notice a segfault when I construct the custom
struct's builder in the constructor's initializer list.
*// Construction that leads to a seg fault*
MyMessageBuilder()
: m_message(),
m_myMsgBuilder(m_message.initRoot<MyMessage>())
{
// The program seg faults in the following line.
m_myMsgBuilder.initSomeStruct();
}
*// Alternate construction does not crash*
MyMessageBuilder()
: m_message(),
m_myMsgBuilder(nullptr)
{
m_myMsgBuilder = m_message.initRoot<MyMessage>();
m_myMsgBuilder.initSomeStruct();
}
0x00000000004059a0 in
capnp::_::DirectWireValue<MyMessage::Which>::set(MyMessage::Which) ()
0x00000000004056fe in void
capnp::_::StructBuilder::setDataField<MyMessage::Which>(unsigned int,
kj::NoInfer_<MyMessage::Which>::Type) ()
0x000000000040551d in MyMessage::Builder::initSomeStruct() ()
What could be causing the seg fault?
Thanks
Sune
