Re: [PATCH] PR libstdc++/70940 optimize pmr::resource_adaptor for allocators using malloc

Hi Jonathan,

indeed, fixed by the following patch.  Tested on i386-pc-solaris2.11,
ok for mainline?

The ugly thing about xfailing the affected tests is that they will XPASS
once in a while when malloc happens to return 16-byte aligned memory.
However, I'm reluctant to skip them instead at least while there's a
chance that Solaris will fix 32-bit x86 malloc alignment post Solaris
