Just to clarify, the change is with this method:


BOOL CALLBACK Pdb::EnumLocals(PSYMBOL_INFO pSym, ULONG SymbolSize, PVOID UserContext)
{
	LocalsCtx& c = *(LocalsCtx *)UserContext;

	if(pSym->Tag == SymTagFunction)
		return TRUE;

	Val& v = (pSym->Flags & IMAGEHLP_SYMBOL_INFO_PARAMETER ? c.param : c.local).GetAdd(pSym->Name);
	v.address = (adr_t)pSym->Address;
	if(pSym->Flags & IMAGEHLP_SYMBOL_INFO_REGISTER)
		v.address = pSym->Register;
	else
	if(pSym->Flags & IMAGEHLP_SYMBOL_INFO_REGRELATIVE) {
		if(pSym->Register == CV_ALLREG_VFRAME) {
		#ifdef CPU_64
			if(c.pdb->win64)
				v.address += c.pdb->GetCpuRegister(*c.context, CV_AMD64_RBP);
			else
		#endif
				v.address += (adr_t)c.pdb->GetCpuRegister(*c.context, CV_REG_EBP);
		}
		else
			v.address += (adr_t)c.pdb->GetCpuRegister(*c.context, pSym->Register);
	}
	else
	if(pSym->Flags & IMAGEHLP_SYMBOL_INFO_FRAMERELATIVE)
		v.address += c.frame;
	c.pdb->TypeVal(v, pSym->TypeIndex, (adr_t)pSym->ModBase);
	LLOG("LOCAL " << pSym->Name << ": " << Format64Hex(v.address));
	return TRUE;
}

- and I believe the problems you are enduring is in there too. So perhaps if you have a bit of time and energy and my change does not work, could you please test with some RDUMPs put there, like


BOOL CALLBACK Pdb::EnumLocals(PSYMBOL_INFO pSym, ULONG SymbolSize, PVOID UserContext)
{
	LocalsCtx& c = *(LocalsCtx *)UserContext;

	if(pSym->Tag == SymTagFunction)
		return TRUE;

	Val& v = (pSym->Flags & IMAGEHLP_SYMBOL_INFO_PARAMETER ? c.param : c.local).GetAdd(pSym->Name);
	v.address = (adr_t)pSym->Address;
      RLOG("-------------------------");
       RDUMP(Format64Hex(v.address));
	if(pSym->Flags & IMAGEHLP_SYMBOL_INFO_REGISTER)
		v.address = pSym->Register;
	else
	if(pSym->Flags & IMAGEHLP_SYMBOL_INFO_REGRELATIVE) {
		if(pSym->Register == CV_ALLREG_VFRAME) {
		#ifdef CPU_64
			if(c.pdb->win64)
				v.address += c.pdb->GetCpuRegister(*c.context, CV_AMD64_RBP);
			else
		#endif
				v.address += (adr_t)c.pdb->GetCpuRegister(*c.context, CV_REG_EBP);
                        RDUMP(Format64Hex(v.address));
		}
		else
			v.address += (adr_t)c.pdb->GetCpuRegister(*c.context, pSym->Register);
	}
	else
	if(pSym->Flags & IMAGEHLP_SYMBOL_INFO_FRAMERELATIVE) {
                RDUMP(Format64Hex(c.frame));
		v.address += c.frame;
        }
	c.pdb->TypeVal(v, pSym->TypeIndex, (adr_t)pSym->ModBase);
	RLOG("LOCAL " << pSym->Name << ": " << Format64Hex(v.address));
	return TRUE;
}
