#4044: Compilation of my ghc tree with ghc-6.12.2 -dcore-lint fails.
-------------------------------+--------------------------------------------
Reporter: milan | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.12.2 | Keywords:
Os: Linux | Testcase:
Architecture: x86_64 (amd64) | Failure: GHC rejects valid program
-------------------------------+--------------------------------------------
In the middle of the work on GHC backend I triggered a bug in GHC. After
discussing with simonpj, I have snapshotted the source tree, as I could
not reduce the test case.
When compiling with ghc-6.12.2 -dcore-lint, the compilation fails in the
stage 1. It is enough to invoke 'make' in the tree to get to the
compilation error. I attach the dump of -dcore-lint output.
The file causing the bug is compiler/cmm/CmmSpillReload.hs. On line 131,
there is a description of a change that makes the source compile.
