[Ipopt] Help: It seems like setting options is not working

[Stefan Vigerske]

Hi,

my guess is that something is wrong with the handling of strings, maybe 
some clash in using different libstdc++ libraries?
Maybe you can investigate with otool -L whether Ipopt uses the libraries 
that you (or your compiler) thinks it should use.
