Recently the 32-bit runtime test started to FAIL on Solaris (both SPARC and
x86):

Maybe ... but if you modify LTO code for a feature I'd expect you
try LTO on a simple example using that feature ;)

One always has to weight in testing time of course.

I thought so myself when I saw the patch and fired off an
i386-pc-solaris2.10 bootstrap.  Unfortunately, the failures remain.

Yeah, I didn't think that would fix this problem, I was just hoping for more
consistent error messages--e.g., "out of memory" rather than "caught signal
while mallocing: 10".

I've now looked a bit closer and found that runtime_SysAlloc is indeed
failing.  The problem seems to be documented behavior of mmap(2) in
32-bit processes on Solaris:

     The size requested is incremented by the 16 Kbytes for these
     pages  and is then subject to rounding constraints. The con-
     straints are:

         o    For 32-bit processes:

                If length > 4 Mbytes
                        round to 4-Mbyte multiple
                elseif length > 512 Kbytes
                        round to 512-Kbyte multiple
                else
                        round to 64-Kbyte multiple

E.g. for os/check, I find almost 50000 512-byte allocations, each of
which costs 64 kB of virtual address space.  This will quickly exhaust 4
GB, while not being a noticable problem for 64-bit processes.
