Hello,

I still get pd crash, even with "iem_tab" load first :
$ cat .pdsettings
...
loadlib1: iem_tab
loadlib2: Gem
loadlib3: pdstring
loadlib4: zexy
loadlib5: tcpserver
loadlib6: tcpclient
loadlib7: pdlua
loadlib8: boids3d
loadlib9: boids2d
loadlib10: pdgst
loadlib11: pix_gst2pix
nloadlib: 11


Here the output with valgrind (with gdb bellow) :
