Euphoria 4.1 Linux 64 bits crashes during recursion

Hi,
Euphoria crashes during recursion with a wrong message:
html_parser.e:231 in function scanTag()
subscript value 2 is out of bounds, assigning to a sequence of length 1
The part of code which is executed is the following:
158 public function scanTag(integer f_out)
230 analyzeSequence(section, "section", f_out)
231 section[$] = append(section[$], scanTag(f_out) )
238 return section
239 end function
Euphoria tells me it couldn't append to section[$] but this is wrong: it did the job!
Before the crash (after executing line 230)
section[1][1] = 'a'
section[1][2][1] = 'href="http://s.s/search?q=abiquo+%22openstack+compute%22?page=1&expansion=1&engines=google&lang=en&ui=stat"'
After the crash (crash routine)
section[1][1] = 'a'
section[1][2][1] = 'href="http://s.s/search?q=abiquo+%22openstack+compute%22?page=1&expansion=1&engines=google&lang=en&ui=stat"'
section[1][3][1][1] = 'TEXT'
section[1][3][1][2] = ' '
Regards
Jean-Marc

Same problem occurs with euphoria_4.0.5_amd64.deb. Nota: I use the modified version of http.e to use set_proxy() function. I don't think this can cause the crash, but it might be important to notice.

I think I got the trick: in section[$], $ does not refer to the correct length. It has not been updated correctly when returning from the recursive call. Regards Jean-Marc

I found the error: it was mine.
Variable section was defined outside of the recursive function, that's why section[$] did not have the right value!
There is no bug. Mea Culpa, ...
