The SHOPT_2DMATCH code block in sh_setmatch() modifies the 'ap' pointer, which is initialised as nv_arrayptr(SH_MATCHNOD). This caused a (rarely occurring) segfault in the following line near the end of the function: ap->nelem -= x; as this line assumed that 'ap' still had the initial value. src/cmd/ksh93/sh/init.c: sh_setmatch(): - On init, save ap in ap_save and use ap_save instead of ap where it should be pointing to SH_MATCHNOD. This also allows removing two redundant nv_arrayptr(SH_MATCHNOD) calls, slightly increasing the efficiency of this function.
