SUMMARY When comparing 2 folders which contain a huge file (>1 GB) and the "Full Analysis" File Comparison Mode option set, kdiff3 will eventually crash (before the initial folder diff comparison is finished, i.e. before the user can interact with the program). When "Binary Comparison" File Comparison Mode option is set, kdiff3 does not crash. STEPS TO REPRODUCE 1. Create 2 folders with a huge file (this will take a LOOONG time; feel free to create the files some other way): $ cat do_test.sh #!/bin/bash mkdir tmp1 mkdir tmp2 for outer in {1..20000} ; do echo "outer=$outer" >> tmp1/tmp.dat echo "outer=$outer" >> tmp2/tmp.dat echo $RANDOM >> tmp1/tmp.dat echo $RANDOM >> tmp2/tmp.dat for _inner in {1..9999} ; do VAL=$RANDOM echo $VAL >> tmp1/tmp.dat echo $VAL >> tmp2/tmp.dat done done for outer in {1..100} ; do for _inner in {1..999} ; do VAL=$RANDOM echo $VAL >> tmp1/"tmp$outer.dat" echo $VAL >> tmp2/"tmp$outer.dat" done done kdiff3 tmp1 tmp2 # EOF $ ls -lh tmp1/tmp.dat -rw-r--r-- 1 erich erich 1.1G Oct 3 08:04 tmp1/tmp.dat $ ls -lh tmp1/tmp1.dat -rw-r--r-- 1 erich erich 5.5K Oct 3 08:04 tmp1/tmp1.dat 2. Use kdiff3 to diff folders tmp1 and tmp2, making sure "Full Analysis" File Comparison Mode option is set (Settings -> Folder -> File Comparison Mode -> Full Analysis). OBSERVED RESULT kdiff3 crashes with the following message at the command line: terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Running under gdb produces the following stack trace: $ gdb kdiff3 GNU gdb (GDB) 11.2 Copyright (C) 2022 Free Software Foundation, Inc.

Inferior 1 [process 81111] will be killed. Quit anyway? (y or n) y EXPECTED RESULT No crash Yes I realize using kdiff3 to compare 1 GB files is nonsensical. My use case is to compare program output from multiple runs, where the output contains both huge files and small files that I actually want to compare. It's also nice to see if the huge files are exact matches or not (indicated by red or green in the directory overview pane). SOFTWARE/OS VERSIONS Linux/KDE Plasma: Slackware 15.0 (available in About System) KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION I can currently work around this bug by ensuring "Binary Comparison" File Comparison Mode is set. I modified the SlackBuild from here https://slackbuilds.org/repository/15.0/development/kdiff3/ by changing the line: -DCMAKE_BUILD_TYPE=Release .. to -DCMAKE_BUILD_TYPE=Debug .. and also commenting out the 2 lines that strip executable and object files: #find $PKG | xargs file | grep -e "executable" -e "shared object" | grep ELF \ # | cut -f 1 -d : | xargs strip --strip-unneeded 2> /dev/null || true to generate a (hopefully) useful backtrace. The observed behavior is the same for Release and Debug builds of kdiff3.

I updated to 1.10.7 and it seems I still get the same error. Follow the same steps as before, and here is the new backtrace. Note that on first opening kdiff3 it is set to "Binary Comparison". After loading the directories to diff I change it to "Full Analysis" and then rerun the diff, which produces the crash. erich@Thelio-PC:~/data/system/pkgs/kdiff3/tmp $ gdb kdiff3 GNU gdb (GDB) 11.2 Copyright (C) 2022 Free Software Foundation, Inc.
