Two common workflows to troubleshoot heap corruption specifically are.
Either approach should allow you to accurately identify an exact call stack related to the heap corruption as long as all your source code projects produce Microsoft pdb files matching their binaries (libraries and exes). See also: Debugging with Symbols, PageHeap vs Pagalloc, What is Pagalloc.
