More on the OS X crashes

[Gregory Wright]

Hi,

I've built a compiler with debugging turned on and have obtained
what might be useful information about the crashes on OS X.

When I try to do a build, in this case, of NewBinary, I get

--->  Configuring hs-NewBinary
DEBUG: Executing proc-pre-com.apple.configure-configure-0
ghc-6.4.2: internal error: ASSERTION FAILED: file GC.c, line 4356

     Please report this as a compiler bug.  See:
     http://www.haskell.org/ghc/reportabug
Error: Target com.apple.configure returned: shell command "ghc -lintl  
-o Setup Setup.lhs -package Cabal" returned error 254
Command output: ghc-6.4.2: internal error: ASSERTION FAILED: file  
GC.c, line 4356


(The ghc output lines are bracketed by some darwinports status info.)

I've seen the same assertion failure in other cases, but it is
not entirely repeatable.  Smells like something is not initialized
or aligned correctly.  (I even got this error from compiling

main = putStrLn "Hello, World!"

but that hasn't happened again since I built ghc over.)

And for some reason when I build ghc on OS X with debugging turned
on, I need to explicit link in -lintl or I miss a symbol that libbfd  
or libiberty is
looking for. But that is probably neither here nor there.

The assertion being violated is

     ASSERT(frame < bottom);

and it's not surprising that things rapidly go pear shaped if this  
isn't true.

Any ideas on how to proceed?  Just as a test, I built a compiler  
using GC.c
from 6.4.1 but it quickly segfaulted.  I just had a hope that the  
significant changes
may have been local to the GC.c file.  This is evidently not the case.

Best Wishes,
Greg
