[0.73b1] About firegl_FreeBuffer() failed! message

[Vivien]

While playing with the 0.72b2 version this message was already here without consequences on the game ( 274). But now the game crash randomly with all the scripts i tried (test script, sometimes; AAI, NTAI, always; Air combat, never ?, etc)
I noticed it arrive more often when i start to build something. I reported it on mantis with my specs: (284)
