Well, iCEBREAKER, you are an inveterate dickish troll. But I also know you to be seemingly quite intelligent and knowledgable. So with that as a preface, I am going to ask...
This is the first I have heard about some flaw in Bitcoin Cash's address format. Where can I find a factual description thereof?
What a nice thing to say about me. I'm flattered!
It's astonishing and hilarious that you are burning the last of your "dry powder" on Altcoin Cash even as you lack the basic familiarity with the local terrain required to perform due diligence on such a brave investment.
Here, I'll do your homework for you. But before the final exam you need to master the material yourself!

BCH users are sending own money into BCH-SegWit addresses 😂 this is invalid and their money is mostly lost. So they will beg the Miner-Kings to return funds 😂. Also, karma is a BitCH (👩🐶) - all could be avoided if BitcoinCash would use custom address prefix instead of pretending to be the Bitcoin.

In the short while since segwit activated on the BTC network and segwit addresses even-more-recently became the default for receiving BTC in the Trezor wallet - and perhaps other wallets too (soon?) - people have started accidentally sending their BCH to BTC-segwit addresses.
Due to the fact(s) that...
a) the BCH network supports P2SH (i.e. addresses starting with 3), but not segwit
... and ...
b) the sending wallets thus have no way of knowing that P2SH-wrapped segwit addresses really are "hiding" a segwit redeemscript
... there's currently no way to prevent this, and it will continue happening.
Examples
(These are just the ones that I've noticed, but I'm sure there are many more that go straight to the various wallet service providers' support teams instead of via Reddit.)

To add insult to injury, the unlucky BCH owners are routinely told that there's no way to recover the coins (including by myself at the start) due to BCH not supporting segwit. And while that's currently true, it is ultimately only a half-truth.
After all, segwit opponents have often said that the satoshis in segwit addresses would be "anyone-can-spend" if the miners didn't enforce the segwit rules (i.e. ensuring that there's a proper witness/signature in the "segregated" part of the txs).
And on the BCH network the segwit rules aren't being enforced!

TL;DR Toomim, Zandar, Todu, Deadalnix, and Jonald have succeeded only in turning their clown fiesta of a fork into a full-fledged Springfield Tire Fire.
Bonus: Trezor is sick of Bcash's bullshit and won't change its address format (you need me to spoon feed you that link too?).
