This unblocks something on my to-do list! Detecting and dealing with #IntegerOverflow in C is a mild ball-ache and so I've been using that as my excuse to procrastinate. 2/n

🎩✨ Oh joy, yet another riveting exploration of integer overflow checks – because who wouldn't want to dive into the thrilling world of compiler flags and conditional branches? 🤔🔍 Surely, decoding a branch on #x86 is everyone's idea of a fun-filled weekend! 😂🚀

CW: Integer overflow
Integer overflow! Integer overflow!
The battery is labeled 44Ah.
The charger shows -24534 mAh.
Assuming this thing uses an int16 to store the charged capacity its now at 41 Ah charged, which is totally fine for a "dead, to be scrapped" car battery.
(Yes I am doing silly off-grid stuff again)

@hywan gcc is not wrong though. You need to check upfront with a decent bounds check that what you will do is OK in C, rather than do it, then see if something undefined happened.
Unfortunately there weren't good tools in the C or C++ stdlib to do checking for a long time.
For C++: https://learn.microsoft.com/en-us/cpp/safeint/safeint-library
C from c23 has builtins to do this, and each common compiler does too:
