two algorthims fail -fsanitize = address

[pm100]

I turned on a bunch of gcc sanitizers

set(CMAKE_CXX_FLAGS "-g -O0 -Wall -Wextra -pedantic-errors -fsanitize=leak -fsanitize=address -fsanitize=undefined ")

This picked up the three leaking programs I reported before. Plus it detected

and

Thanks for reporting this! These sanitizers seem very helpful, I'll add them to the build process.

i have pending fixes for these as well. Have been out of country for a while, hence the silence
