I was looking at Logging Output and had been trying this particular command -
set logging overwrite on
AFAI understood it, that command is supposed to overwrite the contents of gdb.txt but it does not. Is there a bug there or I haven't understood the meaning/syntax properly.
I am running -

Looking at : Bugs in package gdb (version 7.12-6) in unstable
does not tell me much but then I'm no gdb expert or even an intermediate user. If somebody knows a bug which references the above behaviour please share that or if I'm lacking in understanding, please share that as well.
The exact commands are -
$ gdb qbittorrent (gdb) set logging overwrite on (gdb) set pagination 0 (gdb) run
when the application hanged/crashed via -
QXcbConnection: XCB error: 3 (BadWindow), sequence: 16699, resource id: 14227177, major code: 40 (TranslateCoords), minor code: 0 pure virtual method called terminate called without an active exception Thread 1 "qbittorrent" received signal SIGABRT, Aborted. __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 51 ../sysdeps/unix/sysv/linux/raise.c: No such file or directory.
I did the requisite -
(gdb) bt (gdb) bt full (gdb) thread apply all bt
Now I was expecting that with the
overwrite on command gdb will overwrite the contents of gdb.txt from the current session as well as overwrie the time-stamp of the file, neither happened. Luckily, I hadn't closed the session so was able to copy the debug session contents to the maintainer and upstream so they could take a close look at what happened.
I am curious/not understanding as to why it didn't do the changes or am I understanding it wrong.
