The compiled symphony.exe seems to be good, it could solve exmip1.mps 
without any problem.

With the attached pk1.mps (in attachment pk1.tgz) i get this error after 
a few minutes running:

Unhandled exception at 0x0043539f in symphony.exe: 0xC0000005: Access 
violation reading location 0x00df8003.

This is the call stack:

symphony.exe!CoinWarmStartBasis::getStructStatus(int i=45)  Line 85 + 0xc

elementValue=0.00000000000000000)  Line 2614 + 0x2a

symphony.exe!OsiSymSolverInterface::branchAndBound()  Line 93 + 0xc
symphony.exe!main(int argc=3, char * * argv=0x00323278)  Line 46

We can e-mail You the value of any variable if needed.

The exception is deterministic and reproducable. I have not expreinced 
this problem under Linux.

Please help us fixing the problem.

------------------------------------------------------

In my last bug report i was mistaken, the IDE changes the working 
directory by default and it confused me. I was correct, as that 
exception is thrown at line 473, but because the program could not find 
the mps file as the working directory was changed. Sorry for this, this 
is my mistake.

With thanks and regards,
