CrashDoctor 1.0

CrashDoctor protects your programs from crashing due to invalid memory access and other errors CrashDoctor is a program developed to recover crashing programs. It works as a JIT windows debugger and activates when a windows program crashes. It then attaches to the program and tries to recover the program from crashing state by careful analysis of the program.
CrashDoctor has another useful feature, once a program crashes, CrashDoctor monitors the execution of the program. If the program tries to open an existing file for writing CrashDoctor intercepts this and copies the original file to a backup location.
This prevents any further damage done by the misbehaving program. The current version of CrashDoctor however doesnt prevent this if program already has these files open.
CrashDoctor also works like a debugger chooser. After installing CrashDoctor if a program crashes, the CrashDoctor recovery screen shows up. This screen lists debuggers available on the system and you can select a debugger to debug the crashing program instead of recovering its crash. Note here that once you start debugging the program, you wont be able to recover it.
Few words about Crash
A crash can happen in a process due to various reasons like accessing invalid memory locations, resource constraints, resource unavailability etc. One thing to note here is that a crash almost always occur due to bad programming such as not handling error conditions properly.
CrashDoctor tries to recover all the crashes, sometime the crash is so fatal that repeated attempts to recover it fails and in such case, CrashDoctor terminates the process and displays the exit code of the process.
Main features:
- Runs as JIT debugger so no overhead when no program is crashing
- Extremely light-weight and doesnt slow down the process even when recovering it from the crash
- Once a process crashes, CrashDoctor intercepts if the process tries to open a file for write and makes a backup copy of the file to prevent data loss
- Works as a debugger chooser also if you have multiple debuggers in your system. Upon a program crash, you can chose which debugger to use to debug the program (in case you dont want to recover the process from crashing).
- Comes with an easy to use graphical user interface
- Enhancements:
- Created a version for AMD64
- Improved crash recovery for x86 as well as added enhanced crash recovery for AMD64
- Improved the color-scheme for better readability
