[Ipopt] problem using the Matlab interface with limited-memory update option

[Ian Washington]

Hi All,

I tried using static libraries with the libcoin blas/lapack with gcc 4.3 
(officially supported by matlab R2010b) and everything again builds ok; 
however, this doesn't solve the problem when the limited memory option 
is switched on.

./configure --prefix=/opt/Ipopt-3.10.2/install_x64_mat \
              --with-matlab-home="/opt/MATLAB/R2010b" \
              CC=gcc-4.3 CXX=g++-4.3 F77=gfortran-4.3 \
              --disable-shared \
              ADD_CXXFLAGS="-ansi -D_GNU_SOURCE -fexceptions -fPIC 
-fno-omit-frame-pointer -pthread" \
              ADD_CFLAGS="-ansi -D_GNU_SOURCE -fexceptions -fPIC 
-fno-omit-frame-pointer -pthread" \
              ADD_FFLAGS="-fexceptions -fPIC -fno-omit-frame-pointer 
-pthread"

Anybody have any suggestions  ?

Thanks,
Ian.
