Hello all : I am not sure of the gravity of the situation here. I have a testsuite result on Solaris 10 SPARC for gcc 4.8.2 in which 71(g++) + 30(gcc) unexpected test failures are seen and all but two of them claim "scan-not-hidden". Otherwise I would have a nearly pristine result set. Please see : http://gcc.gnu.org/ml/gcc-testresults/2013-10/msg01379.html There are only two failures there that are not claiming "scan-not-hidden" : FAIL: g++.dg/lto/20091219 cp_lto_20091219_0.o-cp_lto_20091219_0.o link, -O3 -flto UNRESOLVED: g++.dg/lto/20091219 cp_lto_20091219_0.o-cp_lto_20091219_0.o execute -O3 -flto I am hoping that what we see here is some evidence of another symptom that lay outside of the GCC source and thus I can perhaps track it down. Where would I look to get more details on these "scan-not-hidden" faults ? Dennis
