Description Axel Kellermann 2016-08-26 08:57:34 UTC

Application: kdevelop (5.0.0)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-34-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
I'm working on a largeish project with a mixture of roughly 5000 Python and C++ source files.
After starting kdevelop, it starts to parse the source tree, and then crashes with a very high
probability while processing the source files.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 3 Axel Kellermann 2016-09-01 13:03:33 UTC

I'd be happy to help with debugging, but I need some pointers where to start, and what to look for.

Comment 4 Milian Wolff 2016-09-07 00:36:57 UTC

Can you compile KDevplatform + KDevelop with ASAN and see if you spot anything? Or try `valgrind --smc-check=all-non-file kdevelop -s ...`.

Or are you maybe running out of memory?

Comment 5 Axel Kellermann 2016-09-08 19:29:54 UTC

I compiled kdevelop and kdevplatform with ASAN and tested again on two platforms:
1. A laptop with only 4GB of RAM, where memory actually is kind of an issue. kdevelop takes up ~3.5GB of RAM
    and the system starts to heavyly swap out pages. But the limits of the swap partition are never reached, so
    parsing gets very slow, but never runs out of memory.
2. A PC with 16GB of RAM, where memory is definitely no issue.

On both machines ASAN reports the same heap-buffer-overflow error during parsing of cmake files (attached as asan_readCMakeFile_20160908.txt).

Comment 6 Axel Kellermann 2016-09-08 19:31:16 UTC

Created attachment 100989 [details]
ASAN output of heap-buffer-overflow error during parsing of CMake file

Comment 7 Kevin Funk 2016-09-08 20:30:14 UTC

Could that be related to bug 363269? Could you check the CMake file KDevelop is parsing (see debug output). Is it a binary file?

Comment 8 Axel Kellermann 2016-09-08 21:23:55 UTC

I found the problem, and it's actually similar, but not the same as bug 363269. The code base being parsed contains a subfolder with example text in a couple of different asian languages, all stored as .txt files in UTF16LE. The cmake parser seems to not just read CMakeLists.txt and *.cmake, but also generally all files with the extension .txt. Apparently the encoding of the example files is handled correctly, but then the wide characters are given to the lexer that expects chars, hence the one byte buffer overflow reported (just my guess, didn't have a look at all the code involved).

If I delete all the UTF16 files, the whole code base is processed successfully.

So I guess the problem is kind of a duplicate of 363269, but more specific. The cmake parser seems generally to greedy in selecting the files it processes. Could that be narrowed down to only CMakeLists.txt and *.cmake?

Feel free to close this one if you think it's covered by 363269.

Comment 9 Kevin Funk 2016-09-08 21:36:00 UTC

Thanks a ton for the analysis, Axel.

And yes, those two bug reports have the same root cause => I'll merge them.
