Random crash in automake manager with Makefile.am open

[Megan Webb]

Hi,

I've submitted patches for automake manger. And am working on
on more automake manager bugs now.

But getting random crashes when trying to Remove files from a target,
add new target, add existing files to a target.  I'm not able to get a
reproducible do "x then y, then crash", but always crash sooner or later.

Besides working on these bugs, I've not used automake manager in the
past. (didn't know it existed). In the early bug work, only added/removed
subproject and targets. I didn't add/remove files to a target.  I can still
add/remove subprojects and targets without problem. Only have crashes
when I start using "create new file/ add existing files" and have the
Makefile.am open

I had random problems before - and just rebuilt qt, kdelibs, kdebase
with debug symbols to get a full trace.

Sample of my efforts:

Check no kdevelop processes running.

1. Create new project 'test' (c++) - simple hello world
2. In automake manger: RMB on 'test.kdevelop', add new subproject 'foo'
3. RMB on 'foo', add target Program/bin: 'bar'
4. RMB on 'bar' create new file 'f0' (blank file)
5. RMB on 'bar' remove
6. RMB on 'foo', add target Program/bin: 'bar'
7. RMB on 'bar' add existing file and add f0 back.
8. RMB on 'bar' create new file 'f1' (blank file)
9. RMB on 'bar' remove
10. RMB on 'foo', add target Program/bin: 'bar'
11. RMB on 'bar' add existing file and add f0, f1 back.

No crash.

Close kdevelop, check no kdevelop processes running,
delete test project from disk. Start kdevelop:

1. Create new project 'test' - simple hello world
2. In automake manger: RMB on 'test.kdevelop', add new subproject 'foo'
3. RMB on 'foo', add target Program/bin: 'bar'
-- open foo/Makefile.am in the window - so I can watch what happens to
the file.
4. RMB on 'bar' create new file 'f0' (blank file)
-- reload Makefile.am
5. RMB on 'bar' remove
6. RMB on 'foo', add target Program/bin: 'bar'
7. RMB on 'bar' add existing file and add f0 back.
-- reload Makefile.am - at this time I have foo and f0 added twice (the
bug I'm working on)
8. RMB on 'bar' create new file
- crash.

Sometimes I do not crash for sometime, but continue to add/remove target and
files with refresh of foo/Makefile.am and eventually the crash happens.

If I attach gdb when running, I find that the crash line in trace7.txt ends
something like:

0xb7f0914c in QString::unicode (this=0x890126c) at qstring.h:653
653         const QChar* unicode() const { return d->unicode; }
(gdb) p d
$1 = (QStringData *) 0x11


If I do not have foo/Makefile.am open in kdevelop, no crash.

Anyone else get this?

Cheers

Megan
