No. I traced back and found that it didn't happen here: 6/7/2001 http://gcc.gnu.org/ml/gcc-testresults/2001-06/msg00210.html but it did occur here: 7/10/2001 http://gcc.gnu.org/ml/gcc-testresults/2001-07/msg00160.html 7/17/2001 http://gcc.gnu.org/ml/gcc-testresults/2001-07/msg00219.html This interval seems to have been a particularing unstable period for solaris2 on what was then the 3.1 trunk. So unfortunately there aren't any reports in between those listed above which narrow down the exact date when it started for solaris2. Are you able to reproduce it by building a cross-compiler to sparcv9-sun-solaris2.7? --Kaveh -- Kaveh R. Ghazi Director of Systems Architecture ghazi@caip.rutgers.edu Qwest Global Services
