--- Comment #17 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-01-23 15:50:16 UTC --- > g++.dg/torture/pr51344.C: Limit to x86. Note that using 'format' instead of 'cdecl' hangs also on powerpc-apple-darwin9: [karma] f90/bug% time g++-fsf-4.6 pr51344_db.C ^C0.002u 0.006s 1:35.05 0.0% 0+0k 2+7io 46pf+0w ^ | interrupted [karma] f90/bug% time /opt/gcc/gcc4.7w/bin/g++ -c pr51344_db.C 0.036u 0.071s 0:01.50 6.6% 0+0k 16+10io 792pf+0w [karma] f90/bug% /opt/gcc/gcc4.7w/bin/g++ -v Using built-in specs.
