Summary0000369: Software Error: hlds.pred_table: predicate `hlds.pred_table.lookup_builtin_pred_proc_id'/8: Unexpected: can't locate put/5
DescriptionUsing the latest Mercury compiler (git commit fd822d712a8f1170a9fab3d9a1d05dd5e404106b)
Compiling the attached example module yields following exception:
Making Mercury\int3s\stream_put5_bug.int3
Making Mercury\ints\stream_put5_bug.int
Making Mercury\asm_fast.gc\i686-pc-mingw32\Mercury\cs\stream_put5_bug.c
Uncaught Mercury exception:
Software Error: hlds.pred_table: predicate `hlds.pred_table.lookup_builtin_pred_proc_id'/8: Unexpected: can't locate stream.put/5
Stack dump not available in this grade.
Error: system command received signal 1.
** Error making `Mercury\asm_fast.gc\i686-pc-mingw32\Mercury\cs\stream_put5_bug.c'.
Steps To Reproducemmc -m stream_put5_bug
Additional InformationUnfortunately I'm not sure when this bug exactly appeared (the program I used to compile was working fine for a while).
An educated guess is that this appeared after the string.format changes in the compiler.
TagsNo tags attached.

To pinpoint the bug, I've modified the hlds.pred_table.lookup_builtin_pred_proc_id/8 procedure (see attached diff) to also output the module name in the error message, not sure if that is generally useful.
Just thought that put/5 was a little bit too generic.
