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