>Description:
pkgsrc bison dumps core in lib/libIDL on creating stamp-parser
on NetBSD/hpcarm 5.99.59 while packages bison binary built on 5.99.55
(using gcc-4.1.3) works fine.

>How-To-Repeat:
# cd pkgsrc/net/libIDL
# make

then bison segfaults.

>Fix:
bison/hacks.mk already mentions the similar problem on sunpro compiler.
Building bison with -O (not -O2) works around too.
(though probably the bison source has some real problem)
