strget bug ?

[slemouton]

I have isolated a bug with strget : sometimes the reported string is not correct.
Let run the (very simple) attached patch test-strget.zip for a "certain time" and sometimes the string printed in max window is not right....maybe a threading issue or string memory allocation ?
csound~ v1.1.3(vb+)
MacOS 10.13.6
Max 8.1.3
csound 6.14
But maybe it reveals a bug in csound, because I am not able to reproduce my problem with csound 6.10 ...
Thank you for any hint !
