undefined behavior detected by runtime as compiled by g++-12 -fsanitize=undefined #73043
Description
Description
I built v7.0.0-preview.6.22324.4 using gcc-12 -fsanitize=undefined which inserts runtime checks into the compiled C++ code. The default optimization level was used.
There are a number of runtime errors reported when I run my simple gcperfsim C# application. I only ran one program, as I was doing a survey of effectiveness of this tool chain.
Attached is the stderr of the running process. The few I've examined look to be true-positives.
All of these errors need to be investigated and fixed or carefully suppressed.
Reproduction Steps
I have my own hairy build script that wraps the "standard" build scripts. I compile with gcc-12 using -fsanitize=undefined
runtime_error_x64.txt
runtime_error_aarch64.txt
Expected behavior
No runtime errors
Actual behavior
Lots of runtime errors. Each needs to be examined closely.

@AaronRobinsonMSFT is this something we are looking into for 8?

There are series of issues related to sanitizers that I've deferred due to @jkoritzinsky working on getting infrastructure in place - see #74623. We can move this to vNext. I'd prefer to keep it out of Future as it makes it easy to lose track of.
