Comment 2 for bug 1747546

This was my first ever use of a nightly. I have only worked on one schematic but witnessed it with several parts. The problem went away after CVPCB but then came back later. I will be working on other schematics and will try and keep better track of what happens and when.

Subject: [Bug 1747546] Re: Fatal crash eeSchema V5 assigning footprint

Is it specific to a component/footprint/schematic? If you used nightlies for a longer period of time, do you know when the problem appeared?

Title:
  Fatal crash eeSchema V5 assigning footprint

Status in KiCad:
  New

Bug description:
  Application: kicad
  Version: (2018-01-26 revision 54ebd4574)-makepkg, release build
  Libraries:
      wxWidgets 3.0.3
      libcurl/7.54.1 OpenSSL/1.0.2l zlib/1.2.11 libssh2/1.8.0 nghttp2/1.23.1 librtmp/2.3
  Platform: Windows 8 (build 9200), 64-bit edition, 64 bit, Little endian, wxMSW
  Build Info:
      wxWidgets: 3.0.3 (wchar_t,wx containers,compatible with 2.8)
      Boost: 1.60.0
      Curl: 7.54.1
      Compiler: GCC 7.1.0 with C++ ABI 1011

  Build settings:
      USE_WX_GRAPHICS_CONTEXT=OFF
      USE_WX_OVERLAY=OFF
      KICAD_SCRIPTING=ON
      KICAD_SCRIPTING_MODULES=ON
      KICAD_SCRIPTING_WXPYTHON=ON
      KICAD_SCRIPTING_ACTION_MENU=ON
      BUILD_GITHUB_PLUGIN=ON
      KICAD_USE_OCE=ON
      KICAD_SPICE=ON

  When editing a specific component (resistor) to assign a footprint, if
  I browse footprints, select R_1206 handsoldering and double click or
  select "Insert Footprint in board" the footprint browser would crash
  and throw error "Error unmapping vertices buffer:invalid operation".

  After this, the browser would hang and all KiCad windows would no
  longer function until all were killed via Task Manager.

  This happened eveyr time I tried it until I decided to use CVPCB to
  assign the footprint. After that the error was thrown once then
  disappeared and even new parts would not cause a problem.

  This was a file imported from V4 if that matters.
