Debugger crashes with corrupt memory, seems reproducible

[stippi]

On hrev33966, I compiled Debugger and MediaPlayer from hrev34009. Then I run the resulting MediaPlayer executable like this:

generated/objects/haiku/x86/release/apps/debugger/Debugger generated/objects/haiku/x86/debug_1/apps/mediaplayer/MediaPlayer

In the Images tab, I close the tree view handle for MainApp.cpp and open the one for MainWin.cpp below it. Scrolling a bit, I find the entry for MainWin::OpenPlaylistEntry() and select it. I set a breakpoint at the beginning of the function. Then I press the Run button and drop an MP3 into MediaPlayer. On the second invokation of F10, the Debugger crashes reproducibly. Usually, it's the following stack crawl:

Thread 7288 caused an exception: Segment violation
...
[Switching to team generated/objects/haiku/x86/release/apps/debugger/Debugger gene (7283) thread worker (7288)]
0x0028856e in LoadImageDebugInfoJob::Do ()
(gdb) bt

#4  0x006729ed in thread_entry () from /boot/system/lib/libroot.so
#5  0x7003ffec in ?? ()

But the first time I got this crash, I was messing a bit in the variables view before stepping, and then it crashed in realloc().

Oops, this may be important: Before it crashes, it prints to the command line:

DwarfManager::File::Load("/boot/system/add-ons/media/plugins/aiff_reader"): no .debug_info or .debug_abbrev.

Do you by any chance still have a reproducible testcase for this one? At least I haven't managed to replicate it with the steps outlined above.

ping.

Sorry, no time at all. If you can't reproduce anymore, feel free to mark fixed.

Thanks for the update, please reopen if you do happen to encounter it again.
