Bugs and Fixes

Check Your Code First Before Looking to Blame Others, Allan Kelly

• Assuming that the tools are widely used, mature, and employed in various technology stacks, there is little reason to doubt the quality. Of course, if the tool is an early release, or used by only a few people worldwide, or a piece of seldom downloaded, version 0.1, open source software, there may be good reason to suspect the software. (Equally, an alpha version of commercial software might be suspect.)
• All the usual debugging advice applies, so isolate the problem, stub out calls, and surround it with tests; check calling conventions, shared libraries, and version numbers; explain it to someone else; look out for stack corrup- tion and variable type mismatches; and try the code on different machines and different build configurations, such as debug and release.
• Question your own assumptions and the assumptions of others.
• Multithreaded problems are another source of bugs that turn hair gray and induce screaming
