Dear PCRE2 Team,
http://www-look-4.com/
If have a question regarding the direct calls to mmap/VirtualAlloc in, e.g.
sljit_allocate_stack. http://www.iu-bloomington.com/ It is not very clear to me
why they are needed, as a user supplied allocator is available.
https://www.webb-dev.co.uk/
In my environment, where everything is in shared memory, the current approach
doesn't work. https://waytowhatsnext.com/

I changed the coding locally to just call SLJIT_MALLOC and everything works
just as fine. Also 500k http://www.acpirateradio.co.uk/ are not that much
memory in 2020 for a normal memory allocator. No need to bother the operating
system. http://www.logoarts.co.uk/

All the logic simplifies considerably and even the whole "page size" stuff is
not really needed. http://www.slipstone.co.uk/

Would it be possible to include this via a compile time flag? I could even try
to share my coding.

Best regards, http://embermanchester.uk/
