Nothing really in the log to indicate why.

Appreciate the backtrace.

Does your `ctrl/time.ini` file appear to be corrupted?

Is this reproducible (e.g. still happening)?

As for the crash, some NULL pointers appear in that backtrace that shouldn't be there (e.g. the `key` argument to `iniReadDateTime()` is `0x0`) which suggests either the `scfg_t` (stored in the heap) was corrupted, or the stack got corrupted during these calls to ini_file.c functions while parsing `time.ini`.

Since the scfg_t element that's used for key argument isn't a pointer in the first place (it's an array of char), I can't really imagine how it'd be set to NULL even through corruption. So that kind of points to stack corruption (e.g. in functions within ini_file.c).
