AIX shared libraries do not allow overriding and interposition of
symbols by default, which is used to override operators, such as
operator new (and operator delete) in C++. Four libstdc++ testcases
rely on this behavior and fail on AIX. Jonathan and I have decided to
XFAIL the testcases to reduce the noise in the testsuite output.
With the recent libstdc++ testsuite changes, there now are only four
(4) failures in the libstdc++ testsuite on AIX -- all due to one real
bug in the C++ front-end for targets with stabs debugging.
Thanks, David
* testsuite/18_support/50594.cc: XFAIL on AIX.
* testsuite/ext/mt_allocator/check_new.cc: Same.
* testsuite/ext/pool_allocator/check_new.cc: Same.
* testsuite/27_io/ios_base/storage/11584.cc: Same.
