Log Message:
-----------
IntlDurationFormat's collectElements() should keep a String alive while
accessing it's data.
https://bugs.webkit.org/show_bug.cgi?id=281849
rdar://138308113
Reviewed by Yijia Huang.
collectElements() was grabbing an 8 bit span from a String's backing store
without keeping
the String alive. As a result, the backing store would be freed immediately
before the
span is accessed. This patch stores the String in a variable explicitly to
keep alive past
the lifetime of the span.
This issue was detected by running
JSTests/stress/intl-durationformat-digital.js with an
ASAN build.
