ASAN_OPTIONS=log_to_syslog=true leads to deadlock #1714

Open dilyanpalauzov opened 10 months ago

dilyanpalauzov commented 10 months ago

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?
