That only took care of the small threads testcase I gave (verified with ~2000 runs). But there seem to be other, separate issues. I discovered other segfaults during 'test all'. An small, easily reproducible testcase is test/io/nonblock/test_flush.rb, which is fixed by compiling with the -fno-tree-dce compiler option. I've now tried gcc-4.7 4.7.0-9 from sid; I found that it fixes the small threads testcase (no need for -fno-optimize-sibling-calls any more); but the test_flush.rb testcase still always segfaults unless -fno-tree-dce is used.
