Summary: double free in rxnformat.cpp/obconversion.cpp
Initial Comment:
When RXN format output is created from from OBReaction there is a segfault in
line 261 in obconversion.cpp:
if(pInStream && NeedToFreeInStream) {
delete pInStream; <<<<<<<< here
pInStream=NULL;
NeedToFreeInStream = false;
}
I think this has something to do with the following portion of rxnformat.cpp:
OBConversion MolConv(*pConv); //new copy to use to write associated MOL
MolConv.AddOption("no$$$$",OBConversion::OUTOPTIONS);
MolConv.SetAuxConv(NULL); //temporary until a proper OBConversion
My suspicion is that pInStream is getting deleted twice - through the original
OBConversion object and through the MolConv copy.
