Or more likely a code bug that ends up using uninitialised data - and
changing the optimisation changes the memory layout.
The gcc flag to annotate the .s file with variable names (IIRC -fverbose-asm)
can help align the asm with the C.
You can also use 'asm volatile ("#comment");' to get comments into the .s
file - but they might change the generated code slightly.
