assert in rts/Schedule.c

[Karel Gardas]

Hello,

I'm curious if I'm the only one seeing asserts like:

Stdout:

Stderr:
PolyKinds09: internal error: ASSERTION FAILED: file rts/Schedule.c, line 528

     (GHC version 7.5.20120103 for arm_unknown_linux)
     Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
Aborted


This happen a lot during testsuite run. As far as I see, threaded1 tests 
are affected at least. Platform is ARM/Ubuntu 11.10 + LLVM 3.0 (from 
ubuntu packages) + GHC HEAD:

$ ./ghc-stage2 --info

  ]


settings looks:

$ cat settings
[("GCC extra via C opts", " -fwrapv"),
  ("C compiler command", "/usr/bin/gcc"),
  ("C compiler flags", " -fno-stack-protector  -Wl,--hash-size=31 
-Wl,--reduce-memory-overheads"),
  ("ar command", "/usr/bin/ar"),
  ("ar flags", "q"),
  ("ar supports at file", "YES"),
  ("touch command", "touch"),
  ("dllwrap command", "/bin/false"),
  ("windres command", "/bin/false"),
  ("perl command", "/usr/bin/perl"),
  ("target os", "OSLinux"),
  ("target arch", "ArchARM {armISA = ARMv7, armISAExt = [VFPv3,NEON]}"),
  ("target has GNU nonexec stack", "False"),
  ("target has .ident directive", "True"),
  ("target has subsections via symbols", "False"),
  ("LLVM llc command", "/usr/lib/llvm-3.0/bin/llc"),
  ("LLVM opt command", "/usr/lib/llvm-3.0/bin/opt")
  ]
