cargoTarpaulin broken- permission issue

[ngerstle-cognite]

https://github.com/ipetkov/crane/pull/49 seems to have broken my use of cargoTarpaulin- reverting the cargoBuildCommand from

cargoBuildCommand = "cargoWithProfile tarpaulin";

to

cargoBuildCommand = "cargo tarpaulin";` 

in lib/cargoTarpaulin.nix avoided a number of permission denied panics:

nix flake check #.x86_64-linux.app-tarpaulin
error: builder for '/nix/store/92x8a0ba5lxbvq0zrgb57dxr7yjm9i7z-app-tarpaulin-0.1.0.drv' failed with exit code 1;

Hmm thanks for the report @ngerstle-cognite! Do you have a minimal repro of the error?

I don't mind reverting the tarpaulin change, but I'm really curious why setting a --release flag would make tarpaulin fail that way

I'll see if I can put something together.

@ngerstle-cognite were you able to get a minimal repro of this?

I'm probably going to tag another release sometime this week, but we can always revert the tarpaulin change later as well, so no rush

Closing due to inactivity and because I haven't been able to reproduce this. Feel free to reopen if you have more info!
