5e937e6e20 Panic on alloc::oom instead of calling intrinsics::abort (#375) 2017-12-15 09:20:50 +01:00

cf2c5550aa Fix sign extension bug in next_table_address (#372) 
Fixes #362

Fix an issue where the left shift of the old table address would overwrite the sign extension, making the address non-canonical and leading to #GPs. This calculates the correct sign extension for the new table address.
