error[E0275]: overflow evaluating the requirement only with incremental build involved

[upsuper]

Steps to reproduce:

1. clone https://github.com/upsuper/telegram-rustevalbot (and checkout 2502973017d39a867dc2cde089b535127bc86e3b which is what I'm currently seeing)
2. run cargo build
3. then run cargo build again

It builds correctly in step 2, but fails in step 3 and shows the following error:

(Note: this projects always rebuild because its build script uses git-version which tricks cargo to rebuild even when nothing changes.)

Further note: if I remove the incremental directory in target, then it builds again. But after that, it fails again.

I have verified that it reproduces in both my macOS and a Linux VPS.

A largely simplified version: testcase.zip

I guess the incremental build somehow pushes some stuff closer to the limitation, and thus triggers this error while non-incremental build doesn't, since removing many of the steps would have the error resolved.
