  • ext/bigdecimal/bigdecimal.c (VpAlloc): avoid ALLOCA_N() to avoid segmentation fault caused by (insanely) long decimal values. [ruby-dev:37189] fix #794
  • ext/bigdecimal/bigdecimal.c (BigDecimal_dump, BigDecimal_to_i, BigDecimal_to_f, BigDecimal_to_s, BigDecimal_split, BigDecimal_inspect): ditto.
  • ext/bigdecimal/bigdecimal.c (VpToString): small performance improvement.
