Closing this old bug.
-It could not be reproduced in order to debug it
-Moreover, the steps given to reproduce refer to an old search/replace method. The corresponding code has changed since.

It was not what I meant. The crash I was just talking about has nothing to do with the replacement of compound mathematical expressions. My mistake.
I had no recent crash when replacing math expressions, but merely because I did less such replacement. I will keep you informed when another crash happens.

Ok, so it is finally a "classic" "view admit no editor" crash. I mark it has duplicate.

I had just a crash because I didn't use TeXmacs a lot. It was a classic "view admit no editor" crash, that happens when you play with clone windows.
This crash produced a report, as always not really readable. I could not do a "backtrace full" afterwards because the program exited correctly.
That's it.

Since you compiled it with enable-debug, you can "simply" use gdb:

1) type:
$ gdb texmacs.bin
in a terminal.

2) in gdb, type
(gdb) run

3) play with texmacs and crash it.

4) in the gdb console, type
(gdb) bt full

5) paste the output here. :)

I'm using the svn trunk, and I have just recompiled globally with enable-debug.
But I don't expect Texmacs to fix the bug, since I regularly recompile globally.
BTW, how can I get a more readable crash_tree?

Thanks. I cannot reproduce the bug on my TeXmacs. If you are using the svn trunk, could you please to recompile it globaly? (by make clean && make)

Indeed, it is not the easiest thing to do in Texmacs:
-Select the mathematical piece of formula you want that you want to replace. Then Edit -> Copy To -> Search (or Ctrl+Shift+C S).
-Select the math that you want to replace by. Then Edit -> Copy To -> Replace (or Ctrl+Shift+C R).
-Put you mouse inside a math formula. Edit -> Replace (or Ctrl+H)
-Leave the "Replace" and "Replace by" field blank and press Enter.

In order to reproduce: how do you search or replace "compound mathematical expressions"?

My Texmacs crashes at least once or twice a day for different reasons. I do not know how to reproduce the crashes, the crash message is not helping

texmacs.bin: ./Texmacs/Texmacs/texmacs.cpp :79 : void clean_exit_on_segfault(int): L'assertion « false » a échoué.

my crash_report_tree is unreadable (see file attached).

What I can tell is that searching or replacing compound mathematical expressions has made my Texmacs crash many times. Please tell me if I can do anything to gather more informations on my crashes.
