I downloaded the sources from
http://bluez.sf.net/download/bluez-hcidump-1.42.tar.gz
and compiled with the following commands:
$ ./configure --prefix=/home/nmarci/usr/local/bluez-hcidump --enable-debug
--disable-pie
$ make
Then I run hcidump with gdb:
$ su
# gdb ./src/hcidump
(gdb) run
Starting program: /home/nmarci/src/bluez-hcidump-1.42/src/hcidump
HCI sniffer - Bluetooth packet analyzer ver 1.42
device: hci0 snap_len: 1028 filter: 0xffffffff
After this point I run the previously attached MIDlet on the Nokia
6288 phone. The result is the same: "Segmentation fault":
