patch 9.0.2141: [security]: buffer-overflow in suggest_trie_walk
Problem: [security]: buffer-overflow in suggest_trie_walk
Solution: Check n before using it as index into byts array
Basically, n as an index into the byts array, can point to beyond the byts
array. So let's double check, that n is within the expected range after
incrementing it from sp->ts_curi and bail out if it would be invalid.
Reported by @henices, thanks!

INSTALLami.txt - Installation of Vim from source on Amiga and MorphOS This file contains instructions for compiling Vim. If you already have an executable version of Vim, you don't need this. The file "feature.h" can be edited to match your preferences. You can skip this, then you will get the default behavior as is documented, which should be fine for most people. Summary: make -f Make_ami.mak gcc make -f Make_ami.mak CC=vc vbcc Please note that currently only gcc has been tested. VBCC would need its own CFLAGS, but should otherwise work out of the box. For cross-compiling, UNM can be used to override uname and thereby set the target. An example is shown below: make -f Make_ami.mak CC=ppc-morphos-gcc UNM=MorphOS
