I am interested to know if someone has done some work to integrate BLCR (Berkely Lab Checkpoint/Restart , https://ftg.lbl.gov/CheckpointRestart/CheckpointRestart.shtml) into gdb? As a standalone, BLCR is quite helpful in certain debugging scenarios. But it is a bit hard to use with gdb , i.e. breakpoints can not be saved and restart is not convienent to stop at certain point etc. BLCR's limitation is it is only for Linux x86 and x86_64. It also needs to load kernel modules which may or may not be an issue. It is not targeting debugging but rather process management/fault tolerance.
