OK. I'll see if I can reproduce the problem. I have been side-tracked from using Kicad working on the build process (now fixed), and studying the source to see if I can offer my own code for geographically renumbering PCB reference designations and back-annotating.

It may take a while to get back to you.

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

If you managed to reproduce the problem reliably and now it stops, then I will be even happier to hear that.

I assume you have followed "Building using MSYS2" paragraph in the official documentation. If so, you will need to create another subdirectory in the source directory and rerun the cmake line replacing "-DCMAKE_BUILD_TYPE=Release" with "-DCMAKE_BUILD_TYPE=Debug", followed by the usual make and make install commands. You will also need to install gdb itself ('pacman -S mingw-w64-x86_64-gdb' command in the
msys2 shell).

Once it is done, you will get a KiCad build with debug symbols. The next step is to run KiCad with gdb (simply launch 'gdb kicad' in the msys2 shell). In the gdb command prompt you need to execute 'run' command to actually start KiCad. Once you manage to crash it, type 'bt' in the gdb shell and post it here.

Many thanks for your cooperation, please let me know if any of the instructions is not clear.

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.
