seems like you found an interesting issue...I'll look into it
was this a specially crafted .lep file?

[seviezhou]

Yes, it is a crafted .lep file, maybe not valid.

[danielrh]

Ya it's not a valid file, but thanks for reporting. We generally use assert to validate the file format since the idea is to run a separate copy of lepton for each decode to enable jailing
