Actaully, I _was_ able to reproduce this.

Crash confirmed on Windows debug build of origin/master (68bf978)

Fails with call stack:

gsicc_new_iccsmask(gs_memory_s * memory=0x504c1010)  Line 175     

gsicc_initialize_iccsmask(gsicc_manager_s * icc_manager=0x01dce810)  Line 194

gs_begin_transparency_mask(gs_state_s * pgs=0x01dbe050, const 

gs_transparency_mask_params_s * ptmp=0x000ce500, const gs_rect_s *
pbbox=0x000ce4d8, int mask_is_image=0x00000001)  Line 587

zbegintransparencymaskimage(gs_context_state_s * i_ctx_p=0x01dce970)  Line 324

When the icc_manager has a 'memory' pointer that is NULL (0x00000000)

Interestingly, the profiles that are initialized (such as default_gray) have
valid 'memory' pointers.

Assigning to Michael Vrhel, but someone else might be able to track this down
since it is so easily reproduced.
