Devel::Size v0.71 and older causes Perl to segfault if you total_size() any non-trivial coderef. This was known as bug 29238 and bug 26781. I fixed/patched this. The patch (for 0.71; probably works on other version, if not, just make the two simple changes manually) is simply:
48c48
< if ((o->op_type = OP_TRANS)) {
---
> if ((o->op_type == OP_TRANS)) {
309a310
> break;

I’m a morning person. 8am is late to me. I’m also a late-evening person. I sometimes work from 8am to 10pm (with breaks for eating). I’ve learned time and time again that programming late-day, or whenever you’re tired, is truly a waste. I spent 7 hours late yesterday trying to perfect ReportFormatter–a rolled-my-own Perl module for generating columnized reports of insanely variable-width data. I was close, but whenever I’d fix X, Y would break, and vice-versa. I forced myself to quit, go home, eat, drink, sleep and in 3 hours this morning I redesigned the module and it works. The design and code is also nicer, unlike the hackish code I was desperately trying to munge into working order yesterday. All that wasted effort for,

That looks simple, but so do many things which are complex under the hood. It’s amazing how simple it is to do in ones mind. Perhaps that’s why coding such a thing is difficult when one’s mind is fatigued, when the idea-code translations come out as logical as dreams.
