At r161673 on x86_64-apple-darwin10, a new failure...

FAIL: gcc.dg/matrix/transpose-3.c execution,    -fprofile-use
-fipa-matrix-reorg -fdump-ipa-matrix-reorg -O3 -fwhole-program -combine

has appeared. This manifests itself as...

A backtrace shows...

so apparently the crash occurs in...


  for (i = 0; i < 2; i++)
    for (j = 0; j < 3; j++)
      if (i==1 && j==1)
        continue;
      else
        free (vel[i][j]);
