[PATCH] Fix PR64078

[Bernd Edlinger]

Hi,

we observed sporadic failures of the following two test cases (see PR64078):
c-c++-common/ubsan/object-size-9.c and c-c++-common/ubsan/object-size-10.c

For object-size-9.c this happens in a reproducible way when -fpic option is used:
If that option is used, it is slightly less desirable to inline the functions, but if an explicit
"inline" is added, the function is still in-lined, even if -fpic is used.

But it may also happen randomly when the sanitizer tries to dump memory around an object,
that lies next to a non-accessible page, the sanitizer prints "<memory cannot be printed>"
in this case, which is not what the test case expects here.  As a work around I added
a large alignment attribute, to make sure, that the object cannot be at a page boundary.


Boot-strapped and regression-tested x86_64-linux-gnu.
OK for trunk?


Thanks,
Bernd.
