Hi all,
the fix for PR100337 was submitted as da13e4ebebb07a47d5fb50eab8893f8fe38683df.
Thanks for the review Tobias.
@Tobias: You are right, caf_single does not get much testing. But this part
(not providing a stat) is tested multiple times, because of the laziness. Nearly
none of the tests in the testsuite provides a variable for stat.
Will wait two weeks for any errors introduced by this patch before backporting
to gcc-11, ok?
Regards,
Andre
