# This little script parse a list of C files, and extract the TRY blocks of it.

# It can reveal usefull when you have a segfault on exception throwing. This
# is often the symptom that something somewhere got out of a TRY block with
# return, goto, break or such. This is forbiden because some extra cleanups
# must be performed at the end of the block.

# So, if it happens to you, you may find this script usefull: let it extract
# all the TRY blocks of your project, and grep for the forbidden keywords
# given above.

# You obviously have to adapt it to your case. The proper solution would be
# to accept the extra -I pathes from the command line. 
# Patch welcome ;)
