Non-standard compile plus Template Haskell produces spurious "unknown symbol" linker error
Programs that use Template Haskell fail to link when doing a "non-standard" compile. Specifically, compilations with -prof and -dynamic produce this bug, although other flags may as well; it seems that compilations that require the two-stage -osuf flag produce this bug. The error message is always "unknown symbol" but the specific symbol that is allegedly missing varies. Removing the TH block from the code makes the problem go away.
I've provided a minimal example of a program that can reproduce this bug, in the enclosed files Bug1.hs and Main.hs. A typescript demonstrating the error message is also included.
Tested on GHC 7.0.1 and 6.12.1, running under Ubuntu 10.04, both 64-bit and 32-bit. Also tested with 6.12.3 under 32-bit Windows 7.
