[gpsd-users] gpsd, buffer overflow during signal handling

[Paul]

Noticed a little problem with gpsd today.

Launch in foreground and specify a non-existing device,
eg /dev/ttyACM99:

   gpsd -n -N /dev/ttyACM99

produces

   gpsd:ERROR: device open of /dev/ttyACM99 failed: No such file or 
directory - retrying read-only
   gpsd:ERROR: read-only device open of /dev/ttyACM99 failed: No such 
file or directory
   gpsd:ERROR: initial GPS device /dev/ttyACM99 open failed

So far OK, but then CNTL-C gives:

 *** buffer overflow detected ***: gpsd terminated

This is with gpsd 3.15 (revision 3.15-2build1) on Ubuntu 16.04.4 LTS.

Same result if I send a kill signal from another shell.
