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.
