I don't think it is the same problem as the tester you cite above has the problem fixed in 416.gamess sources. It looks like we're big into "stage1" with the last run showing Error: 2x416.gamess 2x435.gromacs 2x436.cactusADM 1x437.leslie3d 1x447.dealII 2x454.calculix 2x465.tonto 2x481.wrf Note that gamess is a build error: dftexc.fppized.f:137:0: internal compiler error: in zero_one_operation, at tree-ssa-reassoc.c:1230 SUBROUTINE CALCEXC(ROA,ROB,FTOTWT,GRDAA,GRDBB,GRDAB, zheev.fppized.f: In function 'zher2k.constprop': zheev.fppized.f:7273:0: internal compiler error: in zero_one_operation, at tree-ssa-reassoc.c:1230 SUBROUTINE ZHER2K( UPLO, TRANS, N, K, ALPHA, A, LDA, B, LDB, 0xaa3596 zero_one_operation /gcc/spec/sb-czerny-head-64-2006/gcc/gcc/tree-ssa-reassoc.c:1229 0xaab013 undistribute_ops_list
