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)

------- 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 ***
