There is a PIC compiler from CCS that I use at work. Every now and then we run across a bug (most of which get quickly fixed by CCS). The latest is a rather bizarre issue where strings are getting mixed up.
Attempting to do something like this:
printf("Value %d", value);
…created output like:
…because somewhere else in the code was this:
The compiler was using the correct format string (to know where to put the %d variable on output) but was displaying the string from a different bit of code.
And that other bit of code was unused (not being called at all).
This may be a compiler optimizer bug, but I found it amusing. I haven’t seen a mixed up printf() issue before.
Until next time…
