 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?
