Well I have isolated the problem and discovered that only after I access a "far pointer" using _farpoke or assmebly code, I get a SIGSEGV Page Fault Error 6. It seems that after I first run the program through RHIDE, when trying to run it again the __dpmi_physical_address_mapping(__dpmi_meminfo *) function fails, though I do free the LFB at the end of the prog using __dpmi_free_physical_address_mapping(__dpmi_seginfo *) whichfails to free it, but when I run the prog in dos though it fails to free the LFB at the end, the program runs again with no trouble. I just played around with RHIDE and it seems that sometime when I debug that error eccours and sometimes it doesn't. Can this be a BUG in RHIDE?
