Qt5,Debian,libtesseract4: Crash on recognition #279
Comments
|
Looks like poppler is crashing. Does it happen also if you just browse to page 58? What version of poppler do you have? I can't reproduce this with poppler-0.61.1. |
|
No crash when browsing page 58. |
|
If debian provides debug symbols (something like Closing here since this is a poppler issue. |
|
Not sure this is poppler related: recognizing with language setting EN does work fine, when seleting DE it crashes. |
|
reproducibly so? The stack trace definitely points to poppler :s |
|
And always and just page 58, or does it depend on previous operations? |
|
The ugly theory is that there is a tesseract memory corruption which corrupts memory which poppler is reading. If it is an issue which appeared only with tesseract-4.0 alpha, then this is certainly a possiblity. In that case it would be tesseracts fault... Try running gimagereader through valgrind to see if you get complaints about out of bound writes or similar. |
|
Yes, page 58 with or without other pages before and always only with language DE, but not with language EN. |
|
Ok yes this is a tesseract memory-corruption issue. Please take it to tesseract-upstream. |
Application crashes when "Recognizing page 58 (58 of 66)" with a specific file (will send Sandro separately) running the newest master. Recently Debian updated libtesseract to version 4 on Testing.
