Summary | 0000278: Compiler crash from bad state variable use. | ||||
Description | If I refer to the wrong state variable in the head of a lambda expression, I can reliably crash the compiler. I have a test case. | ||||
Steps To Reproduce | Attached in the testcase It crashes when I compile it with 'mmc --make' It also crashes in the Java grade. mmc -V prints out the following just before the crash. % Converting parse tree to hlds... % Processing clause 1 for predicate `bug.main/2'... % Processing clause 1 for predicate `bug.build_map/5'... The exception thrown is: Uncaught Mercury exception: Software Error: hlds.make_hlds.state_var: predicate `hlds.make_hlds.state_var.svar_find_final_renames_and_copy_goals'/7: Unexpected: readonly status Stack dump not available in this grade. ** Error making `Mercury/cs/bug.c'.
