Comment (by osa1):

 Not sure if relevant, but I'm currently observing `T5435_v_asm_a`,
 `T5435_v_asm_b` and `T5435_v_gcc` fail with segfault when I compile with
 these settings:

 {{{
 BuildFlavour = quick

 ifneq "$(BuildFlavour)" ""
 include mk/flavours/$(BuildFlavour).mk
 endif

 GhcRtsHcOpts += -O0 -DDEBUG -fPIC -g3
 GhcDebugged = YES
 GhcStage2HcOpts += -DDEBUG

 STRIP_CMD = :
 }}}

 Test suite output:

 {{{

 Somehow `./validate` passes, so I'm guessing one of the parameters I'm
 passing to GHC is making a difference.
