Assertion failed when recompiling

[arturoc]

When using nightly builds version rustc 1.53.0-nightly (7f4afdf02 2021-04-22) the compiler panics. This seems to happen only after doing a full build, then changing something and recompiling.

I'm compiling in release but using the following settings:

[profile.release]
opt-level = "s"
debug = true
codegen-units = 256
incremental = true
lto = false

without the incremental flag the error goes away also this doesn't happen on latest stable 1.51

I have a very similar error (likewise, completed build followed by rebuild, and setting incremental = false works around it)
