# bug-445: AddressSanitizer SEGV in hash_string via makeResource when running controller_unit_test -t…

## Description
AddressSanitizer SEGV in hash_string via makeResource when running controller_unit_test -t test_commit_barrier_reply standalone

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

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

## Root cause
Global xstring table uninitialised in standalone runs: makeString() returns NULL, resobj name becomes NULL, key_add hashes NULL. In full-suite runs test_worker_join.c:520 initialises the table unguarded, so the bug only appears with -t selection.

## Fix
Probe makeString("cbrp-probe") in the group entry; call xstring_table_init(139) only when the probe returns NULL (avoids double init in full-suite order).

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