tests: make ASAN repro use valid eval that throws

morrisonlevi · morrisonlevi · commit f4996137e40a · 2026-02-04T14:55:59.000-07:00
Replace the eval parse-error payload with valid PHP that throws an exception, and catch the exception at the call site. The ASAN SEGV in ddtrace backtrace collection still reproduces deterministically.
