Summary: memory leak with evil SMILES
Initial Comment:
Consider this lovely, innocent looking SMILES:
C[C@+@-@+@-@H]1CCCCO1
Open Babel kindly processes it to yield the canonical SMILES of "C[C@H]1CCCCO1"
Unfortunately, it also leaked around 350 bytes of memory. Each "@" allocates
_tetrahedralMap[atom] = new OBTetrahedralStereo::Config;
without checking to see if that was already allocated. Once this pointer is
re-assigned, there's no way to free the previously allocated memory.
This means that if someone has a public facing OpenBabel server, then I can
slowly make it leak memory.
Mwhahahahah! ... Or something like that. :)
