Hi!
I can reproduce with following script:
Reg=Region(884,1291,104,64)
Reg.highlight(2)
for i in range(1,1000):
print_l(i,":",Reg.text())
on my PC it crashed always(!!!) on counter: 272
Here the log:

Hi! Some more findings:
Using the "reproduce script":
*) It does NOT crash, when OCR finds a text.
*) It crashes also at counter 272 for different Regions/images, however:
-) it does not crash (also not later) when I select a Region with "easy"
background (not many patterns)
-) taking a much bigger region results in no difference
-) finding a word in the meantime makes no difference, the script always
crashes at 272
-) OCR.reset() in the meantime makes no difference, still crash at 272
-) replace Reg.text() to OCR.readText() - same, still crash at 272
-) OCR.readLine(), readWord, readChar are also crashing (different count
(=128)), even tough they
find characters in any pattern.
-) Doing OCR alternatively on word and on non-word patterns let it crash
earlier (at 172)
-) Doing OCR on words only does not crash within 1000 runs
-) OEM=0, PSM=8 also crash
-) OEM=0, PSM=2 also crash
I hope I found some useful information.
I was not able to find a workaround (other than avoiding OCR on non
text).
Good luck
Best Regards
Michael
