#6155: -C causes panic "the impossible happened"
--------------------------------+-------------------------------------------
Reporter: Basti | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 7.4.1 | Keywords: panic, impossible, eden
Os: Linux | Architecture: x86
Failure: Compile-time crash | Testcase: (any)
Blockedby: | Blocking:

--------------------------------+-------------------------------------------
1. Intent
To find out where a segfault arises, maybe by adding debbuging symbols.
2. Method
Compile the program with the flag -C, which should stop the
compiler/linker program after the "Generate C" Phase.
3. Expected result
Compiler generates a file .hc which contains C code
4. Actual result
$ ghc-7.4.1.20120416 -C edentest.hs
addFlag by -C on the commandline:
Warning: The -fvia-C flag does nothing; it will be removed in a future
GHC release
ghc: panic! (the 'impossible' happened)
(GHC version 7.4.1.20120416 for i386-unknown-linux):
pipeLoop: at phase As but I wanted to stop at phase HCc
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
$
5. Further Information
The Compiler used is a patched ("Eden") 7.4.1.20120416. It fails this way
with any compilable file I could try.
