Ah, thanks, that's the problem then: gawk's xmalloc is pickier than 
grep's, and the extra pickiness is incompatible with what dfa.c 
expects.  I see that gawk's xrealloc is also too picky, but gawk's 
xcalloc is OK.  Attached isa patch to gawk.  As this problem does not 
affect grep I'll close the grep bug.
