Invalid token error with nytprofcg

[LordAro]

So I was trying out NYTProf with an existing codebase. Unfortunately, it broke.

Profile format error: token 28 (''), chunk 173852, pos 1917430 (see TROUBLESHOOTING in docs) at <snip>/Devel/NYTProf/Data.pm line 87.

Digging through the codebase shows that the error is actually coming from

devel-nytprof/NYTProf.xs

Line 4974 in 1d2a4de

croak("Profile format error: token %d ('%c'), chunk %lu, pos %ld%s (see TROUBLESHOOTING in docs)",

The codebase is big enough that coming up with a more minimal example would be next to impossible, but is there anything I can do to debug it further?

By the looks of things, the content of nytprof.out around byte 1917430 (0x1d41f6) (assuming that's where it's referring to) is (by way of piping it through xxd):

That's about as much as I can show you, I'm afraid

Do you get any better results with the latest version (6.07) of Devel-NYTProf, released this morning (https://metacpan.org/pod/Devel::NYTProf)?

Thank you very much.
