Comment(by simonmar):

 I just added a test for stack alignment for #5250, and sure enough it
 fails with LLVM:

 {{{
 =====> 5250(optllvm) 23 of 23 [0, 0, 0]
 cd . && '/64playpen/simonmar/validate/inplace/bin/ghc-stage2' -fforce-
 recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-conf
 -rtsopts  -o 5250 5250.hs -O -fllvm spalign.c  >5250.comp.stderr 2>&1
 cd . && ./5250    </dev/null >5250.run.stdout 2>5250.run.stderr
 Wrong exit code (expected 0 , actual 1 )
 Stdout:
 esp not aligned correctly: c39c5d30
 }}}
