Memory leak related crash?

[cpalermo-sharper]

I'm experiencing a strange crash during a search where GrepWin seemed to run out of memory. After that the entire machine froze and became unresponsive.

This was the first time this kind of crash happens with this specific dataset.

Unfortunately, without reproducing the issue, it is hard to do anything.
And "the first time" should be a reasonable exemption.
