I can reliably crash J by running: clear'' NB. clear base locale require 'graphics/gl2 api/gles' coinsert 'jgl2 jgles' testdlls=: 3 : 0 try. wd 'pc testopengl;minwh 10 10;cc g opengl;pclose' 'OpenGL OK.' catch. wdpclose 'testopengl' 'OpenGL create context failed. OpenGL not available.' end. )
followed by a short pause and then testdlls'' If I omit the initial (clear'') the crash does not occur. 9!:14'' j803/2014-10-19-11:11:11 Please let me know if you cannot reproduce this crash using these steps.
