[Bug debug/105036] Missing variables when debugging due to overlapping ranges after unrolling, instruction scheduling, and inlining at -O3

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105036 --- Comment #2 from Cristian Assaiante --- Indeed, we understand some information may be lost for the sake of keeping debug info correct. We reported this in the first place because, besides the missing variables, a wrong function (i.e., foo)
