Android crash with RangeError: Maximum regex stack depth reached #29402
Description
Description
Hi there,
we're just trying add some regex to verify user input in the product,
but somehow it will crash directly by some specify user input on Android (iOS worked perfectly)
our regex is to verify user email format like following
/^(?=.{6,80}$)([A-Za-z0-9_\-]+[\.]?)*[A-Za-z0-9_\-]+@([A-Za-z0-9_\-]+)\.([A-Za-z0-9_\-]+[\.]?)*([A-Za-z0-9_\-]*[A-Za-z][A-Za-z])$/I;
and user input is 'aaaaaaaaaabbbbbbbbbbcccccccccc'
crash point is at Hermes, which show RangeError: Maximum regex stack depth reached, js engine: hermes
, but a strange thing is that , once enable debug mode from Developer Menu, it won't crash any more
