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 (100cb77f4) detected at atomics.c:30
[5561ce1e.5287:10] STATEMENT: SELECT test_shm_mq_pipelined(16384, (select string_agg(chr(32+(random()*95)::int), '') from generate_series(1,270000)), 200, 3);
[5561ce0c.51b7:26] LOG: server process (PID 21127) was terminated by signal 6
[5561ce0c.51b7:27] DETAIL: Failed process was running: SELECT test_shm_mq_pipelined(16384, (select string_agg(chr(32+(random()*95)::int), '') from generate_series(1,270000)), 200, 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:
