Changes (by alexander.vodomerov at gmail.com):

  * architecture:  x86_64 (amd64) => x86
  * resolution:  fixed =>
  * severity:  major => normal
  * keywords:  => selinux
  * testcase:  =>
  * version:  6.4.1 => 6.6.1
  * status:  closed => reopened
  * type:  bug => feature request

Comment:

 The same (or at least similar) occurs on x86 with GHC 6.6.1. The compiler
 cannot even
 start.

 GHC 6.6.1 from Debian package

 Distro: Debian GNU/Linux Unstable (Lenny)

 Arch: x86

 Kernel: vanilla 2.6.22.4 Linux kernel

 SELinux policy: refpolicy-targeted (from Debian package)

 I would like to provide additional details, but I can't understand how
 to debug GHC. gdb shows completely brain-damaged stack dump.
