            Bug ID: 31129
           Summary: elf/tst-stackguard1-static and
                    ntpl/tst-stackguard1-static failing on
                    sparc64-linux-gnu
           Product: glibc
           Version: 2.38
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: glaubitz at physik dot fu-berlin.de

  Target Milestone: ---
            Target: sparc64-linux-gnu

On Debian unstable on sparc64 (sparc64-linux-gnu), the following two tests are
failing:

FAIL: elf/tst-stackguard1-static
FAIL: nptl/tst-stackguard1-static

Full build log in [1].

For 2.37, the two failures don't show but I'm not sure whether these are
actually simply not tested for 2.37 [2].

I don't see these with my testing on a sparc64 machine from gentoo project. I
don't use the system compilers, so I am not sure it is subject to any
out-of-tree patch. Do you have any more information, like a debugger output, to
narrow the issue?

Let me try to run the tests in gdb to obtain a backtrace.

--- Comment #3 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Note: issuing elf/tst-stackguard1-static with an argument will hit an issue on
how we define glibc test long options, where support/test-driver.c fails to
append a final zero-filled element:

diff --git a/support/test-driver.c b/support/test-driver.c
index f0fd7ccda2..8cf06793b4 100644
--- a/support/test-driver.c
+++ b/support/test-driver.c
@@ -155,6 +155,7 @@ main (int argc, char **argv)
     {
       CMDLINE_OPTIONS
       TEST_DEFAULT_OPTIONS
+      { NULL, 0, NULL, 0 }
     };
   test_config.options = &options;
 #endif

Could you check with this argument as from the following command?

$ make test t=elf/tst-stackguard1-static

For instance, on the system I built with --enable-hardcoded-path-in-tests (no
need

to setup the GCONV_PATH/LOCPATH/LC_ALL environment for this test):

$ gdb --args
/home/azanella/projects/glibc/build/sparc64-linux-gnu/elf/tst-stackguard1-static
--command
"/home/azanella/projects/glibc/build/sparc64-linux-gnu/elf/tst-stackguard1-static
--child"

Backtrace for tst-stackguard1-static

Sending the backtrace as an attachment because it previously resulted in my
account being banned due to a false positive detection from the spam filter.
