--------
Bug report for Octave 3.0.5 configured for i386-apple-darwin
Description:
-----------
Running 3.0.5, installed using the Fink package manager, on Mac OSX a
segmentation fault is produced by the following sequence.
(1) help <m-file in control>
(2) edit <m-file in control>
(3) help <m-file in control>
Where <m-file in control> may be replaced by any m-file in .../octave/
3.0.5/m/control/base/. For example, both "place" and "bode" produce
seg-faults for me.
Repeat-By:
---------
octave:1> help place
-- Function File: K = place (SYS, P)
Computes the matrix K such that if the state is feedback with gain
K, then the eigenvalues of the closed loop system (i.e. A-BK) are
those specified in the vector P.
Version: Beta (May-1997): If you have any comments, please let me
know. (see the file place.m for my address)
/sw/share/octave/3.0.5/m/control/base/place.m
Additional help for built-in functions and operators is
available in the on-line version of the manual. Use the command
`doc <topic>' to search the manual index.
