Details:

On mingw 3.4.3 and 3.4.2, win7-x64, no packages loaded,
running the following code cause a segmentation violation:


m=10000;
n=32;
temp=randn(m,n)+i*randn(m,n);
b=temp'*temp;
+verbatim-

The crash may happen also when running several time with smaller m:


m=100;
n=32;
for ii=1:1000
  ii
  temp=randn(m,n)+i*randn(m,n);
  b=temp'*temp;
end
m=200;
n=32;
for ii=1:1000
  ii
  temp=randn(m,n)+i*randn(m,n);
  b=temp'*temp;
end
+verbatim-

On my system, the crash occurs on the second loop when ii=11.
