Unfortunately I can't to reproduce this behavior locally.
I built the 32-bit debug mesa + 32-bit debug piglit and have the following
results:
   asimiklit at asimiklit-pc:~/projects/piglit32$ bin/glslparsertest
   tests/spec/arb_shader_storage_buffer_object/compiler
   /unused-array-element.comp pass 4.50 
   ir_variable has maximum access out of bounds (1 vs 0)
   Aborted (core dumped)

glslparsertest and mesa 100% have 32-bit architecture:

   bin/glslparsertest: ELF 32-bit LSB shared object, Intel 80386,

   with debug_info, not stripped

   PS: I know that 1802 in the folder name isn't a correct name
       for the latest mesa folder name but I just forgot to update it in prefix
:-)


Mark could you please clarify which mesa configuration is used
with 32-bit piglit, debug or release? Because I see the same behavior
just with a release mesa configuration.
