| Hello octave maintainers !
| 
| Octave Mingw 3.2.0 crashes on my XP SP3 machine when :
| a. certain eval commands are executed within function after octave startup
| b. clear functions command is executed
| 
| I am attaching a test function code (testf1.m) and listing hereafter some examples which lead to such crashes.
| The examples have been run immediately after octave startup.
| 
| % example A - crash, no exception notice:
| [a,b]=testf1('b=4;a=testf1(''a=1;'',''a'');','a','b'); % ok
| clear functions % crashes, no exception notice
| 
| % example B - above line function calling succeeds when it is called in two stages but crashes when clearing functions, no exception notice:
| a=testf1('a=1;c=3;','a'); % ok
| [a,b]=testf1('b=4;a=testf1(''a=1;'',''a'');','a','b'); % ok
| clear functions % crashes, no exception notice
| 
| % example C - crashes with windows Application Error popup:
| [a,b]=testf1('b=4;a=testf1(''a=1;c=3;'',''a'');','a','b'); % crashes
| 
| Example C above generates an windows application error popup: 
| The instruction at "0x7c9104fa" referenced memory at "0xfffffffd", The memory could not be "read".
| Click OK to terminate the program
| 
| I have followed some threads regarding the possibility that SWIG related packages are causing these crashes so I have tried the above examples also after executing
| pkg unload all
| and still having these crashes.

I don't see the file attachment in your message.  Did you forget to
attach it?

There is no need to cross post your message to three lists.  If you
think you've found a bug in Octave, then the appropriate list is
bug at octave.org.
