Remove uninitialized use of new_crr in erl_alloc_util
When the offending code is reached, new_crr is either uninitalized or have been set to NULL. This patch removes the following warning: beam/erl_alloc_util.c:3510:6: warning: variable 'new_crr' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] if (!(flags & CFLG_FORCE_MSEG)) { ^~~~~~~~~~~~~~~~~~~~~~~~~~ beam/erl_alloc_util.c:3567:23: note: uninitialized use occurs here DEBUG_SAVE_ALIGNMENT(new_crr); ^~~~~~~ beam/erl_alloc_util.c:674:51: note: expanded from macro 'DEBUG_SAVE_ALIGNMENT' UWord algnmnt__ = sizeof(Unit_t) - (((UWord) (C)) % sizeof(Unit_t));\ ^ beam/erl_alloc_util.c:3510:2: note: remove the 'if' if its condition is always true if (!(flags & CFLG_FORCE_MSEG)) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ beam/erl_alloc_util.c:3438:23: note: initialize the variable 'new_crr' to silence this warning Carrier_t *new_crr, *old_crr; ^ = NULL
