# bug-208: ASAN LeakSanitizer: detected memory leaks in scheduler testsuite — build exits with error code

## Description
ASAN LeakSanitizer: detected memory leaks in scheduler testsuite — build exits with error code

## Environment
_Not recorded (migrated from buglog.json)._

## Reproduction
_Not recorded (migrated from buglog.json)._

## Root cause
sched_meet_host_selection() lazily allocates w->host_eval_ctx via build_host_eval_ctx(). Four test functions (test_meet_host_selection_always_true_passes, test_meet_host_selection_always_false_fails, test_meet_host_selection_numeric_match, test_meet_host_selection_string_match) called zarray_fini() without first calling sched_worker_release_host_ctx() to free the lazily-allocated host_eval_ctx.

## Fix
Added sched_worker_release_host_ctx(&w) calls before zarray_fini() in all four affected test functions.

## Verification
