#16166: Compiling with profiling on Windows can cause linker errors -------------------------------------+------------------------------------- Reporter: crockeea | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Keywords: | Operating System: Windows Architecture: | Type of failure: Compile-time Unknown/Multiple | crash or panic Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I've attached code that is a drastically trimmed down version of the `warp` library, which depends only on `base` and `bytestring`. I've added a dummy executable, and when compiled with `stack build --profile warp`, results in the following linker errors on Windows: {{{ Linking .stack-work\dist\e626a42b\build\linkerr\linkerr.exe ...
