--- Comment #12 from kwanza.p...@virginmedia.com --- Just to close issue, I can confirm that this bug affects some applications (not all) that depend on poppler-qt5. Those that use poppler-glib are not affected. Moreover, QT5 is not the source of the problem - given that xpdf works fine, yet is uses QT5 but not poppler-qt5. Therefore, I concluded that some function in okular and texstudio calling libpoppler-qt5.so.1 does not allocate memory properly which then causes libpoppler-qt5.so.1 to fail with the "bogus memory" warning. Searching online, I came across this explanation for a similar issue with a different app using an old version of poppler. << "Bogus memory allocation size" is given by gmallocn(), gmallocn3(), or greallocn(). It is not raised by the memory exhaust, but by the checking of invalid argument (e.g. requested memory size ... numMember x sizeOfMember > INT_MAX, etc). ... >> Anyway, just my 2 cents worth of explanation. -- You are receiving this mail because: You are the assignee for the bug.
