fs-uae has a bug which results in segmentation faults when using
newer versions of the proprietary nVidia driver [1,2]. Initially,
this was blamed on the nVidia driver but it turned out to be a
bug in fs-uae after nVidia investigated the problem [3].
The actual patch to fix the issue just removes an fs-uae-internal
implementation of the glibc function mprotect() which is the
only change in fs-uae_2.4.1+ds-3.
Since this issue affects multiple users and many of them have
directly complained to me in form of bug reports, I would kindly
ask the release team to unblock fs-uae_2.4.1+ds-3 for Jessie.
I have already uploaded fs-uae_2.4.1+ds-3 to unstable and should
pop up on the buildds quickly. I am attaching its debdiff.
Cheers,
Adrian

+Description: 0003-remove-custom-mprotect-function.patch
+ This patch removes an fs-uae-internal implementation of the glibc function
+ mprotect(). This implementation causes fa-uae to segfault when using
+ recent versions of the proprietary nVidia driver. nVidia has investigated
+ into the issue and identified the problem. Simply removing mprotect()
+ from the fs-uae code base results in the code using glibc's implementation
+ of mprotect() and fixes the segfault.
