Bugs with hibernate/3 and HiPE
Mon Sep 27 18:30:59 CEST 2010
There are several bugs related to hibernate/3 BIF and HiPE:
1. erlang:hibernate/3 simply fails with badarg when called from HiPE.
2. erlang:hibernate/3 simply fails with badarg when called dynamically, in a way that the compiler and the loader cannot replace with the i_hibernate beam instruction.
3. There is a segfault in the garbage collector when calling erlang:hibernate/3 (from beam unless bug #1 is fixed) if the process went through HiPE. This is because erts_garbage_collect_hibernate would not clean up the hipe process state.
These bugs are highly related: 1 and 2 are actually the same bug (hibernate/3 BIF isn't implemented, and apparently wasn't since it was introduced), and 3 causes segfaults with any reasonable test once bug #1 is fixed.
The following patch fixes these issues:
