Summary: readlines() bombs - last line incomplete
Initial Comment:
HP-UX 11 64bit, compiled with HP ansi c compiler.
Python version 2.2.1rc2
>>> f=open(some_big_file)
>>> f.readlines()
Pid 23292 received a SIGSEGV for stack growth failure.
Possible causes: insufficient memory or swap space,
or stack size exceeded maxssiz.
Memory fault(coredump)
Happens when last line of file lacks a terminating \n,
also the file has to be big enough (my example is about
2K in size)
Oddly, xreadlines() can be created, but attempting to
iterate over it crashes before the first line is
returned:
>>> f=open(some_big_file)
>>> lines=f.xreadlines() # OK so far
>>> for line in lines:
... print line # never gets here
...
Pid 23257 received a SIGSEGV for stack growth failure.
Possible causes: insufficient memory or swap space,
or stack size exceeded maxssiz.
Memory fault(coredump)
I'll try 2.2.1 final.
