Subject: [PATCH 158/162] tests: disable TEST_MSGCTL_BOGUS_ADDR in ipc_msg test
on glibc >= 2.31
Starting with commit glibc-2.31~358, on every architecture where
__ASSUME_SYSVIPC_BROKEN_MODE_T is defined, glibc tries to modify the
data provided in the third argument of msgctl call. This results
to segfaults inside glibc if TEST_MSGCTL_BOGUS_ADDR is enabled.
* tests/ipc_msg.c [GLIBC_PREREQ_GE(2, 31) && (__m68k__ || __s390__ ||
(WORDS_BIGENDIAN && (__arm__ || __microblaze__ || __sh__)))]
(TEST_MSGCTL_BOGUS_ADDR): Define to 0.
