 Just to record this issue for further reference. Solaris 10 provides GCC
 3.4.3 as a free compiler. Unfortunately compilation of GHC with this
 compiler fails with:
 {{{

 }}}

 the problem analysis so far reveals that the problematic assembler code
 looks:
 {{{
   17826  .byte 0x3
   17827  .word %r_tls_dtpoff32(gct)
   17828  .byte 0xe0
 }}}

 which seems to be kind of wrong. When I tested this with Solaris 11.1 GCC
 4.5.2 I've not able to reproduce this error so I guess this is kind of
 miscompilation in GCC 3.4.3. Actually this is Solaris 10 update 11
 distributed GCC:
 {{{
 $ gcc -v
 Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs
 Configured with:
 /sfw10/builds/build/sfw10-patch/usr/src/cmd/gcc/gcc-3.4.3/configure

 shared
 Thread model: posix
 gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)
 }}}

 so that may serve as kind of known issue on sparc/solaris 10.
