# PetscStackPop
Pops a function name from the PETSc default stack that tracks where the running program is currently in the source code and verifies the memory is not corrupted. Not Collective


## Synopsis
```
#include <petscsys.h>
void PetscStackPop
```



## Notes
In debug mode PETSc maintains a stack of the current function calls that can be used to help to quickly see where a problem has
occurred, for example, when a signal is received. It is recommended to use the debugger if extensive information is needed to
help debug the problem.

The default stack is a global variable called petscstack.
