Callgrind file that causes the crash

Arch/Manjaro 64-bit, dmd is 2.078.0 from official repositories.

dtools-ddemangle < file crashes with a Range Violation. Cannot seem to get line
numbers other than the line 230 in the message.

Attaching file.

(Unsure if this should be filed towards tools or druntime so please reassign if
in error, or close if invalid.)
