not freed memory blocks on regular exiting
Closed, ResolvedPublic


System Information
Linux 64 Debian Jessie - NVidia GTX 660 Ti

Blender Version
Broken: 2.77 (release), 2.76b

Short description of error
after quitting a fresh installation of the actual blender release via Ctrl-Q
an error occurs in the command line:

Error: Not freed memory blocks: 2, total unfreed memory 0.000732 MB
Blender quit

Exact steps for others to reproduce the error
with a fresh installation, without copying earlier setups

  1. call freshly installed blender from release download
  2. save user settings (to produce the 2.77 folder and subfolders etc)
  3. exit blender
  4. call blender
  5. exit via Ctrl-Q -> Error: Not freed memory blocks: 2, total unfreed memory 0.000732 MB
  6. call blender
  7. quit blender via closing window button of OS -> no error

Probably some different treatment of the quitting processes... ??

This needs a win dev to check… probably some missing memfree in specific windows quit handling?

Can't redo this bug.
Tested on Windows7, official 2.77 release and master (d91316dc672dc1ee69fbd24d2f00124a24b75c6b)

When I confirmed a report T48057, it occurred only once.
I ran blender with --factory-startup option.

Windows 10 Pro 64bits
Blender version: 2.77 (sub 0), commit date: 2016-04-04 23:20, hash: 9c952bb

I'm also unsuccessful full in reproducing this one. Why is this tagged windows? original report came in on Linux 64 Debian Jessie ?

I've reproduced the bug on several builds from 2.57 to recent ones.

Run Blender with -d --factory-startup go directly to the File > Quit menu.

Accessing it from the Ctrl + Q shortcut doesn't cause the leak.

Win 7 64 bit.

Can easily recreate this using steps mentioned by @Vuk Gardašević (lijenstina).

Note: after some further testing related to a bug report, setting the operator_context in the to EXEC_AREA causes the issue. If a confirmation pop-up is called, there is no memory leak.

layout.operator_context = 'EXEC_AREA'
if and context.user_preferences.view.use_quit_dialog:
    layout.operator_context = 'INVOKE_SCREEN'  # quit dialog
