951	"stage2 on sparc dies with ""schedule: re-entered unsafely"""	duncan	benl	"Building a registerised GHC-6.6 on Sparc Solaris or Sparc Linux gives a stage2 with the following problem:

{{{
$ ghc --version
ghc-6.6: schedule: re-entered unsafely.
   Perhaps a 'foreign import unsafe' should be 'safe'?
}}}

This happens for Christian Maeder on Solaris and for me on Linux. It does not seem to be related to {{{SPLIT_OBJS=}}} in the {{{mk/build.mk}}}.

Christian reports that it works for him with gcc-4.0.3 but not gcc-3.4.4, though that was not the only thing different between the two configurations:

{{{
It works with gcc_4.0.3_s10 on
""SunOS leo 5.10 Generic_118833-20 sun4u sparc SUNW,Sun-Fire-280R""

It crashes as above on
""SunOS cni 5.10 Generic_118833-24 sun4u sparc SUNW,Sun-Fire-V240""
with gcc_3.4.4_s10.
}}}

My results do not contradict this as I am using gcc-3.4.6 on Sparc Linux."	bug	closed	normal	6.10.2	Build System	6.6	wontfix		duncan.coutts@…	Unknown/Multiple	sparc		Unknown	N/A
