Description

In some cases I'm not getting a usable backtrace:

==31149==ERROR: AddressSanitizer: use-after-poison on address 0x7f84f99cf87f at pc 0x0000010219cf bp 0x7f861e3023b0 sp 0x7f861e301b60

    #1 0x7f86bbfa012b  (<unknown module>)

This makes it hard to debug the problem.

One workaround is to disable codegen.
