With the clang 17 ASAN+UBSAN, I also see this failure: FAIL: test-u8-strstr ====================
FAIL test-u8-strstr (exit status: 142) The cause is that the test has a timeout of 5 seconds; however, it needs 7.1 seconds to execute. This patch increases the timeouts, also leaving some slack for QEMU-emulated environments, and using the gdb-overridable idiom from https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=a8d9f4635238f845bb76269a54fbb2c55255d365 . 2024-05-09 Bruno Haible <br...@clisp.org> unistr/u8-strstr tests: Avoid test failure with ASAN. * tests/unistr/test-u8-strstr.c (main): Increase timeout to 50 sec. * tests/unistr/test-u16-strstr.c (main): Likewise. * tests/unistr/test-u32-strstr.c (main): Likewise. diff --git a/tests/unistr/test-u16-strstr.c b/tests/unistr/test-u16-strstr.c index 4906a96f23..3ba2da2759 100644 --- a/tests/unistr/test-u16-strstr.c +++ b/tests/unistr/test-u16-strstr.c @@ -38,8 +38,9 @@ main (void) #if HAVE_DECL_ALARM /* Declare failure if test takes too long, by using default abort caused by SIGALRM. */ + int alarm_value = 50; signal (SIGALRM, SIG_DFL); - alarm (10); + alarm (alarm_value); #endif test_u_strstr (); diff --git a/tests/unistr/test-u32-strstr.c b/tests/unistr/test-u32-strstr.c index 21caa7842f..320ccfbe42 100644 --- a/tests/unistr/test-u32-strstr.c +++ b/tests/unistr/test-u32-strstr.c @@ -38,8 +38,9 @@ main (void) #if HAVE_DECL_ALARM /* Declare failure if test takes too long, by using default abort caused by SIGALRM. */ + int alarm_value = 50; signal (SIGALRM, SIG_DFL); - alarm (10); + alarm (alarm_value); #endif test_u_strstr (); diff --git a/tests/unistr/test-u8-strstr.c b/tests/unistr/test-u8-strstr.c index 791e1c97f4..670a182d0c 100644 --- a/tests/unistr/test-u8-strstr.c +++ b/tests/unistr/test-u8-strstr.c @@ -41,8 +41,9 @@ main (void) case, we're assuming that we're running this test on the same system that we did the check to ensure it has linear performance characteristics. */ + int alarm_value = 50; signal (SIGALRM, SIG_DFL); - alarm (5); + alarm (alarm_value); #endif test_u_strstr ();
