From: "manu at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/34841] 'make check' of libsndfile-1.0.17 fails with gcc-4.2.2 -O2 optimization, OK with -O1 one Date: Mon, 21 Jan 2008 01:53:00 -0000 [thread overview] Message-ID: <20080121011032.17068.qmail@sourceware.org> (raw) In-Reply-To: <bug-34841-13529@http.gcc.gnu.org/bugzilla/> ------- Comment #22 from manu at gcc dot gnu dot org 2008-01-21 01:10 ------- "make check" failing is expected since there is undefined behaviour in the program and we warn about it with -Wstrict-overflow=5 (I guess that we warn with lower values as well, probably simply with -Wstrict-overflow). So this is a duplicate of PR 32102. About the signed/unsigned warnings, it seems a minor issue. But if you still want us to investigate it, please open a new PR (this one got a bit messy). If you include just the relevant floating_point_test.c file and the headers to make it compile (or better, use -save-temps and attach floating_point_test.i), then we can easily reproduce the bug at will and investigate it. Thanks. *** This bug has been marked as a duplicate of 32102 *** -- manu at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |RESOLVED Resolution| |DUPLICATE http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34841
