It appears to have been the same issue - non-long ints spilled on the
stack and loaded back as long int:

Changes:gcc-7 (7.2.0-3) unstable; urgency=high.  * Update to SVN 20170901 (r251583) from the gcc-7-branch.    - Fix PR
target/81504(PPC), PR c++/82040.  * Apply proposed patch for PR target/81803 (James Cowgill), conditionally    for
mips*targets. Closes: #871514.
 

The package built successfully on mips64el now.
