Issue #, if available: N/A
Description of changes:
An underflow occurs on line 160 when
stack_depth
is smaller thanFRAMES_TO_SKIP
(i.e., stack_depth = 1). This occurs on riscv64 where the library fails to obtain a valid trace, which is a separate issue.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
