Qt bug, please report at http://www.qtsoftware.com/developer/task-tracker Bug report has been filed in Qt's bug tracker (hasn't appeared there yet though). I recently got that crash again; if it shows up once more, maybe Iĺl have time to bug someone on #qt about it ;-) I tried to reproduce this bug while running kdevelop in valgrind, this is what I got: ==26642== Memcheck, a memory error detector. ==26642== Copyright (C) 2002-2007, and GNU GPL'd, by Julian Seward et al. ==26642== Using LibVEX rev 1854, a library for dynamic binary translation. ==26642== Copyright (C) 2004-2007, and GNU GPL'd, by OpenWorks LLP. ==26642== Using valgrind-3.3.1, a dynamic binary instrumentation framework. ==26642== Copyright (C) 2000-2007, and GNU GPL'd, by Julian Seward et al. ==26642== For more details, rerun with: -v ==26642== ==26642== My PID = 26642, parent PID = 20102.

write() ==26642== Warning: invalid file descriptor -1 in syscall write() ==26642== Warning: invalid file descriptor -1 in syscall read() Hmm, I might have been wrong about this one. The valgrind log looks suspiciously like a too-early-deleted job problem. This seems to be somewhat reproducible: "Add two targets, hit F8 to build them, abort while still building, then immediately hit F8 again." I often realize there is still a syntax error while the build is already happening, so I re-hit F8. Maybe that is why I saw this crash several times today? Note: I'm running kdelibs from trunk. qt-copy with patches applied SVN commit 933075 by apaku: Don't try to re-use kjob's, thats not going to work. No need to keep track of the jobs now anymore, so remove the member. BUG:185640 M +1 -8 makebuilder.cpp M +0 -1 makebuilder.h WebSVN link: http://websvn.kde.org/?view=rev&revision=933075 |
Version: (using Devel) Compiler: gcc version 4.3.2 [gcc-4_3-branch revision 141291] (SUSE Linux) OS: Linux Installed from: Compiled sources I was building two targets of my application, hit the Cancel Jobs button, made a change to one of the files, and hit F8 again. Attached is the backtrace.
