Description of problem: Builds of hdf-4.2.9-1.fc19 on PPC64 and PPC32 get stuck during the sel checks without any indication what's going on. make check-TESTS make[3]: Entering directory `/builddir/build/BUILD/hdf-4.2.9/hdf/test' make[4]: Entering directory `/builddir/build/BUILD/hdf-4.2.9/hdf/test' ===Serial tests in test begin Tue May 7 14:50:03 MST 2013=== make[5]: Entering directory `/builddir/build/BUILD/hdf-4.2.9/hdf/test' ============================ Testing testhdf At this point it waits until koji gets a timeout and kills it.

I'm at a complete loss. It seems like even "strace -f testhdf" produces no output. I have no ppc machines myself to test with.
It hangs in test_mgr_interlace(1) when dimsize[0] = 4 and dimsize[1] = 5 (around line 2293 in mgr.c) gdb shows more, mcache_look seems to be looping here: 0x00000000100bf100 in mcache_look (pgno=1, mp=0x102eb6e0) at mcache.c:1183 1183 for (bp = head->cqh_first; bp != (VOID *)head; bp = bp->hq.cqe_next) (gdb) p *bp $12 = {hq = {cqe_next = 0x1022ff20, cqe_prev = 0x1022ff20}, q = {cqe_next = 0x10284f50, cqe_prev = 0x102eb6e0}, page = 0x1022ff50, pgno = 4, flags = 0 '\000'} (gdb) p pgno $13 = 1 (gdb) p bp $14 = (BKT *) 0x1022ff20 (gdb) p bp->hq.cqe_next $15 = (struct _bkt *) 0x1022ff20 (gdb) p head $16 = (struct _hqh *) 0x102eb6f0 This looks to me like there is no way to get out of this loop: for (bp = head->cqh_first; bp != (VOID *)head; bp = bp->hq.cqe_next) if (bp->pgno == pgno) { /* hit....found page in cache */ #ifdef STATISTICS ++mp->cachehit; #endif /* done */ ret_value = RET_SUCCESS; goto done; }
sounds like a gcc 4.8 issue, as the test suite passes in f21 with gcc 4.9
