Hi Alex,
when running the mupdf demo on base-linux/x86_64 (make run/mupdf), I get the following error: ... [init -> mupdf] Error: libc suspend() called from non-user context (0x1180506) - aborting
this is another occurrence of a missing 'with_libc' call that is needed whenever a native Genode component calls into potentially blocking libc functions (like 'read'). I fixed the problem at the staging branch [1] now.
