[Ipopt] Output dependency_detector mumps

[Klaas Eggert]

Hello,

we use ipopt 3.9trunk and I want to detect the dependencies of the 
linear constraints.
We get the following output from the option "dependency_detector mumps":

MUMPS used permuting_scaling 0 and pivot_order 2.
            scaling will be 6.

Detected 194 linearly dependent equality constraints; taking those out.

List of indices of dependent constraints:
c_dep[0] = -220
c_dep[1] = -219
c_dep[2] = -218
c_dep[3] = -217
c_dep[4] = -216
c_dep[5] = -215
c_dep[6] = -214
c_dep[7] = -213
c_dep[8] = -212
c_dep[9] = -211
c_dep[10] = -210

...

c_dep[178] = 132
c_dep[179] = 133
c_dep[180] = 134
c_dep[181] = 136
c_dep[182] = 137
c_dep[183] = 138
c_dep[184] = 139
c_dep[185] = 140
c_dep[186] = 141
c_dep[187] = 142
c_dep[188] = 143
c_dep[189] = 144
c_dep[190] = 145
c_dep[191] = 147
c_dep[192] = 149
c_dep[193] = 150


EXIT: Not enough memory.

Without this option ipopt solves our nlp without any errors messages.
Can anybody explain us the output of the dependency detector?

Thank you,
Jan and Klaas
