Target Milestone: ---
Hi,
I m running gcc testsuite with qemu, and I am facing an issue in sanitizer.
Before (12.x), the asan was incompatible with ptrace.
$ cat emtpy.c
int main(void) { return 0; }
$ aarch64-linux-gnu-gcc emtpy.c -fsanitize=address
$ qemu-aarch64 -L ./sysroot-with-libasan-from-release ./a.out
==135765==LeakSanitizer has encountered a fatal error.
==135765==HINT: For debugging, try setting environment variable
LSAN_OPTIONS=verbosity=1:log_threads=1
==135765==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)
# fiishes quickly : return status=1
Now (13.x),
$ qemu-aarch64 -L ./sysroot-with-libasan-from-master-branch ./a.out
# RAM memory grows exponentially without message
It happens of course on most asan-dg.exp tests
Either, it has been changed and not incompatible anymore with ptrace, or the
error message was removed by error.
It happens of course on most asan-dg.exp tests.
Is this supposed to work now ?
