Hopefully Unkillable Stack

This is a generalized stack container header-only library in C with additional debug options like hash calculation, canaries and elem/ptr poison.

Debug options that could be enabled with macro

Debug flag/option	description	traits
STACK_USE_POISON	enables poisoning (filling with predefined value) of stack data	[SLOW]
STACK_USE_PTR_POISON	enables poisoning of structural pointers
STACK_USE_CANARY	enables canaries (arrays of predefined 64bit values on both sides of data) constance of which is checked
STACK_USE_STRUCT_HASH	enables hash calculation of structural values of the stack structure, like capacity, value count etc.	[REQUIRES_SSE4.2]
STACK_USE_DATA_HASH	enables calculation of bitwise hash of data	[SLOW] [REQUIRES_SSE4.2]
STACK_USE_CAPACITY_SYS_CHECK	enables system capacity correctness check (via malloc_usable_size() in unix or _msize() in windows)	[OS_DEPENDENT]
STACK_USE_PTR_SYS_CHECK	enables system pointer correctness check	[SLOW] [OS_DEPENDENT]
STACK_VERBOSE 2	sets the level of log verbosity from 0 to 2; if not defined eq. 0

Building with some debug options

$ mkdir build
$ cd build
$ cmake .. -D CMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} -D STACK_USE_PTR_POISON -D STACK_USE_DATA_HASH -D STACK_VERBOSE=2"
$ make

Building with all debug options

$ mkdir build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=FULL_DEBUG
$ make

Building release version

$ mkdir build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release
$ make
