visual c++ - SAL annotations and new operator overload -


i have problem sal annotations , new operator overloading. want provide new operator not throws exceptions return nullptr in case of error. have written:

_check_return_ _ret_maybenull_ _success_(return != nullptr) void* operator new(_in_ size_t size) {     return malloc(size); }

unfortunately vs2012 see declaration of new provided in <new> header different , after build->run code analysis gives me lot of errors declarations incompatible. chooses declaration provided in <new> indicates new never returns null. have tried remove <new> include not (it included different headers <vector>). how can convince compiler use sal annotations?

can't link nothrownew.obj, if non-throwing new want?

be aware though it's bad idea. 1 thing, stl implementation shipped msvc doesn't expect new return null , doesn't check that, goes right ahead , uses pointer. if use stl, , if run out of memory, instead of bad_alloc exception you'll access violation - hardly improvement.

assembly - 8086 TASM: Illegal Indexing Mode -

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
