https://buildd.debian.org/status/fetch.php?pkg=mlpack&arch=mipsel&ver=2.2.0-1&stamp=1490300651&raw=0
When ggc-min-expand is reduced from 20 to 5 and max-parallel from 2 to 1,
package mlpack successfully passes for mips and mipsel.
I have created and attached a patch that contains the necessary changes.
Regards,
Radovan
