There's a great Random ASCII blog post about an obscure FPU issue like this [1]. - The crash was in a FPU that Chrome barely uses - The instruction that crashed Chrome was thousands of instructions away from the one that triggered the exception - The instruction that triggered the exception was not at fault - The crash only happened because of third-party code running inside of Chrome - The crash was ultimately found to be caused by a code-gen bug in Visual Studio 2015 I've run into this kind of thing once myself (sharing a process with other companies is fun!). It was real confusing to get a stack trace showing our code suddenly crashing on a line of code that was doing the exact same thing with the exact same values as it had always done before.
