 ## [NJOY2016.70](https://github.com/njoy/NJOY2016/pull/xxx)
 This update fixes a number of minor issues:
   - Fixed an issue in HEATR when reading evaluations with large multiplicity tables in MF6.
+  - Fixed a crash in THERMR when asking for S(a,b) processing (iinc=2) while no ENDF tape is given (nendf=0).
   - Multiple ERRORR calls can now be made in the same input file without crashing. This is of interest to users that wish to process MF34 and MF35 (where ERRORR needs to be called for each sub-subsection and incident energy group).
 
 A few compiler warnings have been resolved as well (unused variables). For source files that were corrected in this way, the remaining warnings relate to equality comparisons for real values, unused dummy arguments in subroutines and potential 0 indices into arrays (in all cases, if statements prevented this from happening).
