------------------------------------+---------------------------------------
Enviroment: linux-ppc, very fresh software, upcoming gcc 4.2, ghc 6.6. I
 was trying to build alex software which ended with:
 GNU ld version 2.17.50.0.12 20070128
   Supported emulations:
    elf32ppclinux
    elf32ppc
    elf32ppcsim
 ghc3729_0.hc:(.text+0x104a): undefined reference to
 `ParseMonad_alexStartPos_closure'
 ghc3729_0.hc:(.text+0x104e): undefined reference to
 `ParseMonad_alexStartPos_closure'
 dist/build/alex/alex-tmp/Info.o: In function `shII_info':
 ghc3729_0.hc:(.text+0x106e): undefined reference to `Util_lvl1_closure'
 ghc3729_0.hc:(.text+0x1072): undefined reference to `Util_lvl1_closure'
 ghc3729_0.hc:(.text+0x107a): undefined reference to `Util_lvl1_closure'
 dist/build/alex/alex-tmp/Info.o:(.rodata+0x40): undefined reference to
 `Util_lvl1_closure'


 The problem is that these symbol disappear after going through mangler (so
 problem is visible only when -O2 is used)


 In short the problem is that:
 .globl ParseMonad_alexStartPos_closure
 disappears.
