Is this passing in the existing version ?

The test case malloc/tst-free-errno is an additional failure that was passing before the update but is now failing after the update.

then its a regression if its not intermittent. Maybe worth digging a
bit into this and root cause it.

Hi Khem,

I analyzed the issue further by debugging it manually and observed that the testcase "malloc/tst-free-errno.c" passed as expected. Hence, I ran the testsuite again after the update and found that the issue was not reproduced anymore.
Please find the following results after the update:
*After update*
PASS - 4946
FAIL - 223
XPASS - 4
XFAIL - 16
UNSUPPORTED - 229

*Before update
* PASS - 4924
FAIL - 223
XPASS - 4
XFAIL - 16
UNSUPPORTED - 229

Another intermittent issue it seems. For future I would suggest to do
more than 1 run and save the logs, I also wonder what is the spec of
VM on which these tests are running.
