[Gambas-user] Bug during Webview Eval() usage

[Yahoo]

Hi Benoit,

I have found a bug (Segmentation fault 11) during execution of around 320 Eval() in a short time inside a loop (for each …) in a Webview.

Some time this loop works fine and each Webview1.Eval(cmd) are executed and another time I have this error.

I don’t know if it’s important but I run a Linux Mint 17.2 on virtualBox  machine.
I use the latest SVN release 7227
I tried to execute this project as described on Gambas Web Site with gdb but I get the same error text, no more.

I tried to compile Gambas SVN manually with only QT5 Webkit => Same error
I tried to compile Gambas SVN manually with only QT4 Webkit => Same error

Do you need a little project to reproduce the error because in this case I must create it from the main project ?
