But preferable to taking out the OS with it, as this did to mine for about 10
minutes. I can't remember seeing memory in use expand so quickly. I suppose I
can protect against it (using bash)
ulimit -v 2097152
Then vim reports
E342 Out of memory! (allocating 477061 bytes)
E316: ml_get: cannot find line 1
E320: Cannot find line 1
E316: ml_get: cannot find line 1
7951 substitutions on 0 lines
Press ENTER or type command to continue
It's the undo handling that uses the memory, the problem does not occur with
setlocal ul=-1
