v1.8.9 : IF / ULONG > ULONG() array comparison bug (*solved*)

[JMcGibbitts]

Hello Boriel, my first post here, so I'm sorry it's to report a bug.

I found a problem when comparing a ULONG variable with any entry in an array of ULONGs.
Saving the array entry to a temporary ULONG variable to compare with is a workaround.

The problem seems to happen with v1.87, so is perhaps an older bug.

A working code comparison sample is pasted below. 
The code purpose is to find where to insert a page number in an array of page numbers, where the pages are stored in correct sequence but are not simply incrementing numbers.
Switch between SUBs v1() / v2() to compare the output.

Thanks

Code:
