Description
Hello,
We have an issue with the latest version of PDF service (2.11).
Here is the code to reproduce :my $filepath = "/<path_to>/main2.pdf";NV::Command("NV_CMD=|OBJECT:CREATE| NAME=|file| TYPE=|FILE| PERSIST=|-1| REPLACE=|YES| FILENAME=|$filepath| NV_CONTAINER=|nvdef|");
NV::Command("NV_CMD=|PDF:PDF:GET_TEXT| IN=|file| OUT_TEXT=|out_text| PAGE=|1| AREA=|28,28,427,567| NV_CONTAINER=|nvdef|");
It has been reproduced on Linux32 and Windows 64 (both version 4.7.003).
We could reproduce it with PDF version 2.07, but with version 2.06, the server does not crash. (The content is still weird)

Further investigation showed that the problem is linked to the content of the table, starting with the text:
BL N° 1496510 du 12/06/12 Nre...
Vs Référ Commande 11/06/12...
Notre Réf C.de U 315578...
... and following lines
When we try to copy this text from Adobe Reader, we do not paste text but weird characters.
Hope this will help track down the issue.

The problem has been corrected. This was a bug in X sorting algorithm of the text blocks. Text blocks are first sorted by Y coordinate and then by X coordinate. The issue was in the X sorting. In some situations, the blocks were not sorted correctly and were duplicated. This was producing a crash when deleting duplicated blocks (deleting an already deleted block). The sort algorithm on X has been completly rebuilt.
Regression testing has been made successfully.
PLEASE CONTACT ME TO GET THE BETA VERSION OF THE CORRECTION AND TO TEST ON YOUR SIDE.
