[Bug 34342] Chronic crash of Guild Wars 2(out of memory)

--- Comment #29 from [e-mail] ---
I think Luna Crane has just seen his disk cache in memory growing and is now
thinking in the wrong direction.

But I'm wondering how much glibc affects this as it has a bug which causes it
to not release some memory back to the system:

Maybe somebody can test Wine with another library instead of glibc or compile
Wine with a workaround that it uses malloc_trim() at key points (for example
after every free()) and check if any of these workarounds solves this issue.
