Thanks to @staticfloat's JuliaLinearAlgebra/libblastrampoline#48, we can build julia with ASAN again (once the binary is shipped). This PR mentions the additional required setting LBT_USE_RTLD_DEEPBIND=0 in the sanitizer documentation. In the second commit, I added a subsection mentioning concrete steps (based on @maleadt's setup).

Also, I wonder if we can add ASAN build in the CI? I think I can give a shot at it but I don't know if it's worth pressuring the CI queue.

  • wait for new release of libblastrampoline

I don't know if it's worth pressuring the CI queue.

Don't worry too much about that right now, I say go for it! I suggest copying the llvmpasses buildkite config and adjusting as necessary.

@tkf Feel free to ping me and Elliot if you run into trouble with the ASAN Buildkite job.
