Hi! while compiling luatex, i got an error: xlc -DHAVE_CONFIG_H -I. -I../../../texk/web2c -I.. -I../../../texk/web2c/.. -I/opt/freeware/include -I../../libs/obsdcompat -I../../libs/obsdcompat/.. -I../../../texk/web2c/../../libs/obsdcompat -I../../../texk/web2c/../../libs/obsdcompat/.. -I../../../texk/web2c/../../libs/zlib -I../../../texk/web2c/../../libs/libpng -I../../../texk/web2c/../../libs/xpdf -Dextra_version_info=`date +-%Y%m%d%H` -O2 -qmaxmem=262144 -qarch=com -qlanglvl=extended -qcpluscmt -c luatex0.c -o luatex0.o "luatex0.c", line 8931.5: 1506-117 (S) Operand must be a scalar type.

"luatex0.c", line 9133.11: 1506-117 (S) Operand must be a scalar type. here are the statements on the referenced lines: 8931: eq_destroy ( eqtb [p ]) ; 8940: eq_destroy ( eqtb [p ]) ; 9005: eq_destroy ( eqtb [p ]) ; 9124: eq_destroy ( save_stack [save_ptr ]) ; 9133: eq_destroy ( eqtb [p ]) ; does this make sense to you? eqtb and save_stack is a structure.
