Summary 06097: Most sets in viper.c: Crashing at start (32-bit only)
Description When running most sets with the new official toolchain supplied (GCC 5.2.0) - most sets in viper.c crash immediately upon start.
Please note, this does not happen with earlier toolchains (GCC 4.9.1,4.9.2 tested). Perhaps a compiler error or finally rooting out a problem that has laid dormant?

Compiler error suspected. offset received the value of space, and data received the value of offset.
But if a printf was added, the problem went away.
Rearranged the relevant code and now it works.
