The following function produces a segv when the begin() is taken from
vmap, the ScalarMap...
bool StaticMemAnalysis::isSingleMalloc(DSGraph* theGraph,DSNode* theNode)
{
int count = 0;
std::map<Value*, DSNodeHandle>& vmap = theGraph->getScalarMap();
for (std::map<Value*, DSNodeHandle>::iterator i = vmap.begin(); i
!= vmap.end(); ++i) {
if(i->second.getNode() == theNode) {
if(isa<MallocInst>(i->first)) count++;
}
}
if(count == 1) return true;
return false;
}
This code used to work... Has something changed or is our code wrong? I
rebuilt two days ago...
