The symptoms are that it either reaches a line of code that I don't expect it to (and crashes due to an unexpected type error), or it crashes the entire watch (with ERR_LOG.TXT).
Neither of these things happen in the simulator; also, the peak memory (14.9k) stays below the 16k limit and peak objects is 36. (In a typical configuration.)
In fact this only happened after I made some drastic changes to save several 100 bytes of memory.
Any ideas? Would really appreciate it.
Here's the relevant logs from the latter scenario.
