Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a method to detect vulnerability inducing code elimination by compiler optimization. It is reported that security codes, which are intended to protect programs against invalid memory accesses or to scrub secret information in memories, can be eliminated by compiler optimization. This paper attempts to detect such code elimination by binary comparison. A pair of binary codes are generated from a given source code and are compared; one is obtained with a typical set of optimization options and the other by suppressing the problematic optimization. Since the two binaries are often too different to reveal the code elimination, comparison is done focusing on specific instructions. When the code elimination is detected, the source code is minimized to identify the code fragment that caused the difference. A detection tool implemented in Perl5 has been run on 5 programs consisting of about 200 to 51400 lines, to detect one case of guard elimination and two cases of dead store elimination.
