The code with a problem is:

#include "rob.hh"

template <class Impl>
void
ROB<Impl>::insertInst(DynInstPtr &inst) // Scope of inst is only source.cpp
{
    assert(inst);
    DPRINTF("blah", inst->pcState());
    auto tid = inst->threadNumber;
    bool instTracked = cpu->trackInsts.find(inst->pcState().instAddr()) != cpu->trackInsts.end();
}

When you place ROB<... on the same line as void (i.e., place the function declaration all on one line), the scope of inst changes (becomes more correct).

It looks like:

It should look like:
