[Pkg-octave-devel] Bug#695551: panic: segfault at startup

[Drew Parsons]

Package: octave
Version: 3.6.2-5
Severity: grave
Justification: renders package unusable

octave has just started failing to start, with the error message:

$ octave -q
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault
$ echo $?
139

(so octave exits immediately with error code 139.)

The bug appears also in 3.6.3-2.

The interaction with gdb is odd. An error is found, but the octave
command line appears regardless.  I think octave catches the error,
but doesn't panic inside gdb.  So no backtrace is available. The gdb
behaviour is:
$ gdb octave 
GNU gdb (GDB) 7.4.1-debian
Reading symbols from /usr/bin/octave...(no debugging symbols found)...done.
(gdb) run -q
Starting program: /usr/bin/octave -q
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
error: fclose: invalid stream number = -1
error: called from:
error:   /usr/share/octave/3.6.2/m/pkg/pkg.m at line 463, column 1
error:   /usr/share/octave/3.6.2/m/startup/octaverc at line 21, column 1
octave:1> 

Is the octave-core file useful?

Thanks,
Drew
