Date: Thu, 15 Dec 2022 09:47:29 +0000 [thread overview]
Message-ID: <bug-108124-35322@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108124
Bug ID: 108124
Summary: UBSAN issues when tests are run
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rust
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: dkm at gcc dot gnu.org, gcc-rust at gcc dot gnu.org
Target Milestone: ---
I built GCC compiler with ASAN & UBSAN enabled:
F="-fsanitize=address,undefined -g -O2" ; make -j32 all-host -k CFLAGS="$F"
CXXFLAGS="$F" LDFLAGS="$F"
and I see a couple of issues:
./xgcc -B.
