|

|
||
Note that it's a different issue from Glibc #30068 we've fixed in
|
||
chapter08/glibc.xml with a sed. Normally we just document the
|
||
test failure, but in this case the particular subtest also serves
|
||
as an additional guard against Glibc #30068. So we apply the
|
||
upstream fix here. -->
