Description :
output of "frama-c -deps from.c -slevel 10":
... [from] ====== DEPENDENCIES COMPUTED ====== These dependencies hold at termination for the executions that terminate: [from] Function main: publc2 FROM publc1 \result FROM \nothing [from] ====== END OF DEPENDENCIES ======
However, if "publc1" is located e.g. at address 0x30000, then "p" would point to 0x30004, that is, (possibly) to "secret1", which wasn't mentioned as source location by FromAnalysis.
