panic: array_repeat list path overflows inner element count multiplication #22219
Description
Describe the bug
array_repeat can panic for list inputs when len * count overflows while calculating the repeated inner value count.
To Reproduce
SELECT array_repeat([1,2,3], 9223372036854775807);Actual behavior
thread 'main' panicked at datafusion/functions-nested/src/repeat.rs:245:32:
attempt to multiply with overflow
Expected behavior
Return an execution error for an output-size overflow instead of panicking.

Verified on current main (1e58928): this no longer reproduces.
SELECT array_repeat([1,2,3], 9223372036854775807);now returns a proper execution error (array_repeat: requested length exceeds maximum array size) instead of panicking — the list path uses checked arithmetic since #22274. Suggest closing.
