--- Comment #15 from Zoltan Herczeg <hzmester@???> ---
This temporary file(s) approach is a bit complicated to me, so I finally
decided to allocate separate memory blocks with mmap for each compiled pattern.
This obviously increases the memory consumption, but it solves this problem.
You can try it by downloading the latest source code and set CFLAGS to the
following value before calling configure.

CFLAGS="-DSLJIT_PROT_EXECUTABLE_ALLOCATOR=1"
