Bug ID: 113123
Summary: ASAN_OPTIONS=log_to_syslog=true leads to deadlock
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: dilyan.palauzov at aegee dot org

Created attachment 56928
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=56928&action=edit
The backtrace as a separate file
I filled the same also at https://github.com/google/sanitizers/issues/1714.
I compile software on Fedora 39/ gcc 13.2.1 20231205 with
export CFLAGS="-g -fsanitize=address -fno-omit-frame-pointer -fno-common
-fsanitize=undefined -fsanitize-recover=address"
export CXXFLAGS="-g -fsanitize=address -fno-omit-frame-pointer -fno-common
-fsanitize=undefined -fsanitize-recover=address"
then I set
ASAN_OPTIONS=log_to_syslog=true:log_path=/tmp/c-asan.log:halt_on_error=false:detect_leaks=0"
UBSAN_OPTIONS=log_to_syslog=true:log_path=/tmp/c-ubsan.log:print_stacktrace=1"
LSAN_OPTIONS=verbosity=1:log_threads=1"
and run the software. The software reaches deadlock. I connect to it with gdb.
Below is the full backtrace. I do not know where the ?? at the end come from,
as I have compiled the software with debug information. I cannot write simpler
software, which reproduces the problem.
In any case the software waits forever in the syslog-Futex call.
Can you find, based on the provided backtrace, the root cause for the deadlock?
