Hi guys,<br>
<br>
when validating fix from Ben, I found another interesting thing:<br>
<br>
1) Create quite a deeply nested directory, in my case full path was:<br>
<br>
/home/jv/Projects/Pharo/3.0/<u></u>dsdsadasdsadasdas/<u></u>DasDasDasdASdASdASDasDas/das/<u></u>das/das/dasd/<u></u>dasdasdastget4efdsfsd/<u></u>dasdasdasdasda/dadasdasdasdas/<u></u>dasdasdadasdasdadasdasdasdasda<u></u>sdasdasdsadas/<u></u>dadasdasdasdasrewgdfgbfdcghbcf<u></u>gdf/gdf/gdfgdfgdf/gdfg/df/gdf/<u></u>gdf <br>
<br>
(yes, it's that crazy, nevertheless perfectly valid. 248 bytes in<br>
total.<br>
<br>
2) Download last pharo to the inner-most directory:<br>
wget -O- <a href="http://get.pharo.org/30+vm" target="_blank">get.pharo.org/30+vm</a> | bash<br>
<br>
3) run it:<br>
./pharo-ui Pharo.image<br>
<br>
VM crashes, producing following on stdout/err:<br>
