[Ipopt] (no subject)

[Stefan Brugger]

Hi everybody,
I'm using Ipopt with Mumps in VS2012. If running in debug mode I get for my example a runtime error when Ipopt calls Mumps for solving a KKT system:


****
Calling MUMPS-1 for symbolic factorization at cpu time 4.624 (wall 0.097).
forrtl: severe (408): fort: (11): Subscript #1 of the array ICMP has value -842150450 which is less than the lower bound of 1
...
****

If looking in the Ipopt console output (see attached log file) one sees that some indices seem uninitialized:

******* KKT SYSTEM *******
(0) KKT[1][1] = 0.000000000000000e+000
...
(21) KKT[-842150450][-842150450] = 0.000000000000000e+000
(22) KKT[-842150450][-842150450] = 0.000000000000000e+000
(23) KKT[-842150450][-842150450] = 0.000000000000000e+000
(24) KKT[-842150450][-842150450] = 0.000000000000000e+000
(25) KKT[-842150450][-842150450] = 0.000000000000000e+000

(28) KKT[-842150450][-842150450] = 0.000000000000000e+000
(29) KKT[-842150450][-842150450] = 0.000000000000000e+000
(30) KKT[-842150450][-842150450] = 0.000000000000000e+000
(31) KKT[-842150450][-842150450] = 0.000000000000000e+000

...
(59) KKT[10][10] = -0.000000000000000e+000
...


Have you got any idea what went wrong?

More detailed information about my environment:
I compiled IPOPT 3.9.3 with Mumps with the v8-ifort Visual Studio projects(converted for VS2012) and stlport. I tested successfully the generated dll's with an example file from the Ipopt source tarball.


Best regards,
