Estimated hours taken: 13 Branches: main Mode analysis was aborting in a program where it was inserting a new variable for an implied mode unification, but the new variable id already had a (non-free) mapping in the instmap, which led to a compiler abort (it thought it was about to enter an infinite loop). This problem was introduced when Mark changed modes.build_call with his recent fixes for polymorphism. modes.build_call extracts the module_info from the mode_info, then the proc_info for the current proc from the module_info. However, at this point the proc_info has out-of-date varset and vartypes fields, because mode analysis can introduce temporary variables for implied mode unifications. compiler/modes.m: Ensure that modes.build_call first takes the current varset and vartypes fields from the mode_info and used them to update the current proc_info before using it to construct an initialisation call. tests/hard_coded/Mmakefile: tests/hard_coded/solver_build_call.m: tests/hard_coded/solver_build_call.exp: Added a test case.
