Extended Description
sac2c product version 16651 From the sac repository compile demos/numerical/tvd/tvd_abstract.sac (version 1171) with the following command: sac2c-p -O3 -v1 -maxlur 10 -L fluid tvd2d_abstract.sac -check ctb and it segfaults in DCRvardec (stdopt/deadcoderemoval.c:506). Run sac2c-d -O3 -v1 -maxlur 10 -L fluid tvd2d_abstract.sac -check ctb and stack overflow warnings are produced: WARNING: dbug-maxdepth 40000 too low I enabled the automatic tracing in _db_enter_ in dbug.c and saved the output. The file is quite large so I haven't uploaded it. It is here: obelix:/home/dsr/tvdabstract-autotrace
