# Subject: Infinite loop in sub/gsub
# From: jhart@avcnet.bates.edu

# Message-Id: <4BC4A4F0-D928-11D6-8E78-00039384A9CC@mail.avcnet.org>
#
# This command line:
#
# echo "''Italics with an apostrophe'' embedded''"|gawk -f test.awk
#
# where test.awk contains this instruction:
#
/''/ { sub(/''(.?[^']+)*''/, "<em>&</em>"); }
#
# puts gawk 3.11 into an infinite loop. Whereas, this command works:
#
# echo "''Italics with an apostrophe' embedded''"|gawk -f test.awk
