# seem to be a mechanism to reliably check whether the zeroize calls are being

# WARNING: There does not seem to be a mechanism in GDB scripts to set a
# breakpoint at the end of a function (probably because there are a lot of
# complications as function can have multiple exit points, etc). Therefore, it
# was necessary to hard-code the line number of the breakpoint in the zeroize.c
# test app. The assumption is that zeroize.c is a simple test app that does not
# change often (as opposed to the actual library code), so the breakpoint line
# number does not need to be updated often.
