[Cbc] Problem with a large ILP

[Joachim Schauer]

Hello!

We are trying to solve a "lagre" ILP (~2 million variables and 15000
constraints) and are using CBC (2.8.7) as a standalone solver in a
64-bit Linux with 4GB of RAM. However CBC quickly consumes all memory
and throws the following exception:

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

Is this normal for such an input size, or is there something strange
going on?

Thank you for your help!

Joachim

The input file in lp format can be found here and we are calling it
with: cbc Masterarbeit.lp
