go tool dist: Failed: exit status 1

[zhangfannie]

Allocs-related tests fail because when -asan is turned on, the -checkptr option is implicitly set to 2, which is implemented by CL 393315, so that some stack objects with usafe.Pointer operation will escape to the heap, resulting in additional heap allocation.

[zhangfannie]

For the bug in the assembly function, I will submit a patch to fix it.

As for the issue of allocs tests, we may need to skip these tests when -asan is on. Does anyone have any other ideas? Thank you.

[gopherbot]

Change https://go.dev/cl/543837 mentions this issue: runtime: change the name of variables in asan-related assembly funtions

[bcmills]

As for the issue of allocs tests, we may need to skip these tests when -asan is on. Does anyone have any other ideas?

testenv.SkipIfOptimizationOff seems like it fits the bill — is there some way to make testenv.OptimizationOff return true if the build is using MSAN or ASAN?
