#
# This perl script checks for correct memory function usage in ICU library code.
# It works with Linux builds of ICU using clang or gcc.
#
# To run it,
# 1. Build ICU
# 2. cd icu/source
# 3. perl tools/memcheck/ICUMemCheck.pl
#
# All object files containing direct references to C or C++ runtime library memory
# functions will be listed in the output.
#
# For ICU 58, the expected output is
# common/uniset.o U operator delete(void*)
# common/unifilt.o U operator delete(void*)
# common/cmemory.o U malloc
# common/cmemory.o U free
# i18n/strrepl.o U operator delete(void*)
#
# cmemory.c Expected failures from uprv_malloc, uprv_free implementation.
# uniset.cpp Fails because of SymbolTable::~SymbolTable()
# unifilt.cpp Fails because of UnicodeMatcher::~UnicodeMatcher()
# strrepl.cpp Fails because of UnicodeReplacer::~UnicodeReplacer()
#
# To verify that no additional problems exist in the .cpp files, #ifdef out the
# offending destructors, rebuild icu, and re-run the tool. The problems should
# be gone.
#
# The problem destructors all are for mix-in style interface classes.
# These classes can not derive from UObject or UMemory because of multiple-inheritance
# problems, so they don't get the ICU memory functions. The delete code
# in the destructors will never be called because stand-alone instances of
# the classes cannot exist.
#
