[FROG] ospfd crashes when deleting a route-map

[Amol Lad]

Hi,

I'm using FRR 7.4 (OpenWrt). I'm not using the integrated-config (i.e. each daemon has it's own config file). Below sequence of commands crashes ospfd. Please advise if any more useful debug information I can provide regarding this issue.

# for debugging purposes, you can specify a "wrap" command to start instead
# of starting the daemon directly, e.g. to use valgrind on ospfd:
#   ospfd_wrap="/usr/bin/valgrind"
# or you can use "all_wrap" for all daemons, e.g. to use perf record:
#   all_wrap="/usr/bin/perf record --call-graph -"
# the normal daemon command is added to this at the end.
