[bug-recutils] SegFault in recfix

[OLLIER Jean-François]

recfix crashes when parsing this line:

%unique: first last userId mgrId employeeType mission projectName StartDate
+EndDate building floor room cubicle hostname bus ramSize cpu monitorSize
+monitorNum dropId dropConnected unixAccount

It does'nt if I remove one word from the line.

Here is the crash report:
