Hello Yongheng,

FWIW: Confirmed on 32-bit MIPS with moderately patched 5.4.0 (source
package md5sum dbf155764e5d433fc55ae80ea7060b60).

(gdb) bt
#0  0x7716194f in luaH_getshortstr () from .../usr/lib/
#1  0x77161a69 in luaH_get () from .../usr/lib/
Backtrace stopped: frame did not save the PC

Best regards,
