I'm using patched version of RHIDE-1.4.5 built together with 
sources of gdb-4.16 (instead of 4.17)

I haven't seen anything like. However project files touched with 
1.4.5 are no more usable with 1.4

Known problem with original binaries. Use them to rebuild rhide-
1.4.5 from sources with libgdb from gdb-4.16 instead of 4.17.
Some hacking may be needed.

No crashes for me with patched 1.4.5. However I don't see output 
in mode 0x13. I think that can also crash on different video card
as RHIDE does not handle 256 color modes well.
