Problem with QEMU usermode + jemalloc

[Michael Goffioul]

Hi,

I'm running into a problem using QEMU in usermode and jemalloc (this is in the context of an ARM-to-x86 translation layer for Android). The issue is discussed here:

https://github.com/jemalloc/jemalloc/issues/1844

In a nutshell, the lack of madvise implementation is making jemalloc return non-zeroed memory on calloc. This then creates various crashes in the emulated code.

What would be the QEMU devs point of view on this?

Thanks,

Michael.
