Set Crashes

[J.B. L. <let...@un...>]

Dear Set:

This is very complicated now.

1. First I re-configued and re-compiled and re-installed tvision and
setedit as per your instructions with the CFLAG and CXXFLAG environment
variables set. I used a plain configure, no options.

With this compilation I could NOT crash setedit, with or without gdb.
Neither the editor.exe, nor, later the setedit binary once I had installed
it. I tried compiling again with the no-intl option for both tvision and
setedit. No problems, no crashes. It is definitely the new binary running,
and the "help/About" gives the 5.4 identification.

So: I tried WITHOUT the CFLAG variables set (configure, make make install)
both the editor and the tv libraries, and could not crash setedit
either with the editor.exe or the re-re-installed setedit.

Please note that nothing has changed on the computer in the meantime (at
least as far as I can recall, and I have wrkaced my brains and my log
files); I haven't altered things for months and months now.

BUT: I had accidentally deleted the source tarball for tvision last week,
and had to download another to make these tests: though whether there have
been any changes I wouldn't know.

OK: finally, I re-compiled both tvision and setedit from the beginning,
without the CFLAG variables set, but WITH "--no-intl" as a configure
option for both tvision and setedit. This time it crashed quite happily
and consistently. The --no-intl is my normal option.

I hoe that is a clear account of what I have done. If something seems
illogical or inexplicable, please don't hesitate to ask me to repeat
something.

Below are the results from these crashes.

Note: I normally work from the console. There were problems with recording
the crashes there however (see below), so I switched to Xwindows (where
you have a marvellous interface, may I say), and recorded with no
difficulty the FIRST report below. However, under Xwindows, partly becasue
of the corruption of the keyboard, I couldn't reproduce all the styles of
crash: so I returned to the console with the "hack" which I explain
next to get the other data as best I could.

So: the second group are a bit chaotic perhaps, since, once gdb runs
editor.exe and it crashes it grabs the mouse and the alt and ctrl keys.
So that I had to keep quitting gdb after each crash, paste from a garbled
screen, fix the garbage, re-run gdb editor.exe, run "continue" past the
crashes I already had, and quit and paste the next step, again
from the garbled screen and so on. I have tried to be careful. I have
deleted repeated material.

Finally: the crashes always occur when I try to change console (alt arrow,
or alt F1 etc); AND/OR when I fill in a box, such as the TAGS dialogue
which pops up on Ctrl-Tab: space to check the "don't show next time" box;
return to get rid of the dialogue -- crash. Ditto with "search": enter the
expression, hit return, crash. Also with the dialogue mentioned below
Editor General:check box, press enter, crash.

Sorry to bang on so long: I thought I'd try and give all the information I
could think of.

Let me know if I can or should do anything else.


1. [Under Xwindows]

Program received signal SIGSEGV, Segmentation fault.
0x40073b67 in TStringCollectionCIntl::freeItem ()
   from /usr/lib/librhtv.so.2.0.3
(gdb) continue
Continuing.
I'm sorry but I did something wrong :-(
Look in the file /home/nemle01/.setedit/erY77Yzd for unsaved buffers and information.
Please send this file to the author (se...@ie...).

Program received signal SIGSEGV, Segmentation fault.

2. [Under Console]

[this next as a consequence of pressing Alt+left arrow, to try
and change consoles]

[Ditto, but this is the next "continue" Alt+right this time]

Hope this helps,

All the best,
