Re: [Lmuse-user] crash on saving
Hi André, that's bad :( As I can't reproduce this (not now anyway). Some things to test: 1. does it crash if you resave an empty project? Meaning, do you need to add something specific to the project? 2. start muse with arguments -apNI2D , this will skip connecting jack, loading plugins and turn on debug trace. Does it crash in this scenario? Send the debug trace. 3. recompile muse with debug info. Can be done for instance by modifying the compile_muse.sh and replacing -DCMAKE_BUILD_TYPE=release with -DCMAKE_BUILD_TYPE=debug after installing and before running muse, run the command 'ulimit -c unlimited' to allow the operating system to store core dumps. Now, if MusE crashes in this scenario opening the core file with gdb will hopefully show the problem. Report back and do ask if something is unclear. Thanks, Robert 2015-07-08 12:22 GMT+02:00 André Sklenář andre.skle...@gmail.com: Hiall. i started making some music again, when a most unfortunate thing happened - muse crashed right on ctrl+s, losing my progress exactly at a time i wanted to save it :-/ So i found out that this happens every time you save a project which overwrites a file. This happens with 2.1.x aswell as with 2.2.1. It also crashes regularly when autosave is on. Here is some info on my system. archlinux, 3.14.45-1-lts (but bfs and rt kernels do the same) qt version: 4.8.7. here is a gdb backtrace: Program received signal SIGSEGV, Segmentation fault.
