Dynare++ error message

Dear Musketeers and Ondra D’Artagnan in particular,

dynare++ throws the following error message:[code]
C:\DATA\tmp\GK>dynare++ --threads 8 --prefix k5 NKHTGKEIpp.mod
terminate called after throwing an instance of 'std::bad_alloc’
what(): std::bad_alloc

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application’s support team for more information.[/code]
The soft/hardware is Win XP, 4 GB memory, i7 processor, Dynare++ v. 4.2.5. order = 5;

Does it tell me something about the model? The very same mod file runs ok with order = 3.
