Revision 8b66d778157c5fd1d4db68822b6451abf792ce11 authored by Michael W. Hudson on 02 October 2002, 13:13:45 UTC, committed by Michael W. Hudson on 02 October 2002, 13:13:45 UTC 
Fix for the recursion_level bug Armin Rigo reported in sf
 
patch #617312, both on the trunk and the 22-maint branch.

Also added a test case, and ported the test_trace I wrote for HEAD
to 2.2.2 (with all those horrible extra 'line' events ;-).
