problems on Solaris

Buildfarm members casteroides and protosciurus have been having some 
problems that seem puzzling. These animals both run on the same machine, 
but with different compilers.

casteroides runs with the Sun Studio 12 compiler, and has twice in the 
last 3 days demonstrated this error:
   [5561ce0c.51b7:25] LOG:  starting background worker process "test_shm_mq"   [5561ce1e.5287:9] PANIC:  stuck spinlock

string_agg(chr(32+(random()*95)::int),'') from generate_series(1,270000)), 200, 3);   [5561ce0c.51b7:26] LOG:  server

3);  [5561ce0c.51b7:28] LOG:  terminating any other active server processes
 

It's not constant - between the two failures was a success.

protociurus runs with gcc 3.4.3 and gets this error:
