Hannes, if I understand your code correctly, you used the struct interface* as a flag for "is routing entry fresh?" which is a side effect. Can you please apply 102-olsrd-rt-refactoring-fixes.patch and take a look to the two locations found by "grep fresh src/*.c" ? TIA, // Sven-Ola Hannes Gredler wrote: [TOFU removed] > /hannes
