1.28 + * Default implementation of UMemory::new/delete
1.29 + * using uprv_malloc() and uprv_free().
1.30 + *
1.31 + * For testing, this is used together with a list of imported symbols to verify
1.32 + * that ICU is not using the global ::new and ::delete operators.
1.33 + *
1.34 + * These operators can be implemented like this or any other appropriate way
1.35 + * when customizing ICU for certain environments.
1.36 + * Whenever ICU is customized in binary incompatible ways please be sure
1.37 + * to use library name suffixes to distinguish such libraries from
1.38 + * the standard build.
1.39 + *
1.40 + * Instead of just modifying these C++ new/delete operators, it is usually best
1.41 + * to modify the uprv_malloc()/uprv_free()/uprv_realloc() functions in cmemory.c.
1.42 + *
1.43 + * Memory test on Windows/MSVC 6:
1.44 + * The global operators new and delete look as follows:
1.45 + * 04F 00000000 UNDEF notype () External | ??2@YAPAXI@Z (void * __cdecl operator new(unsigned int))
1.46 + * 03F 00000000 UNDEF notype () External | ??3@YAXPAX@Z (void __cdecl operator delete(void *))
1.47 + *
1.48 + * These lines are from output generated by the MSVC 6 tool dumpbin with
1.49 + * dumpbin /symbols *.obj
1.50 + *
1.51 + * ??2@YAPAXI@Z and ??3@YAXPAX@Z are the linker symbols in the .obj
1.52 + * files and are imported from msvcrtd.dll (in a debug build).
1.53 + *
1.54 + * Make sure that with the UMemory operators new and delete defined these two symbols
1.55 + * do not appear in the dumpbin /symbols output for the ICU libraries!
1.56 + *
1.57 + * If such a symbol appears in the output then look in the preceding lines in the output
1.58 + * for which file and function calls the global new or delete operator,
1.59 + * and replace with uprv_malloc/uprv_free.
