I ruled out a few things, namely it seems to happen with both LinuxThreads and NPTL, so it seems unlikely that the threading library/kernel is at fault. The changes-4.0.1 file says that support has been added for SGI Altix, which means someone must have been interested in getting it working on IA64? Any idea who that person might be? -i signature.asc Description: Digital signature
Bug#343127: qt-x11-free: Will need to be rebuilt for IA64 with updated binutils
Package: qt-x11-free Severity: important Hi, As noted in http://lists.debian.org/debian-ia64/2005/12/msg6.html kdevelop3 crashes the linker when it builds. It turns out this is due to the linker bug (actually a bug from 'strip -g') http://sourceware.org/bugzilla/show_bug.cgi?id=1991 and a fix to the linker has been applied in http://sourceware.org/bugzilla/show_bug.cgi?id=2008 However, this patch will cause the the linker to bail out, rather than crash, so the package still won't build. A rebuild of these libraries will be required when an updated binutils is available, I have asked the binutils people about this in #342777 -i signature.asc Description: Digital signature

Package: libqt4-core Version: 4.0.1-5 Followup-For: Bug #342658 I built your program like this $ qmake-qt4 -project test.cpp $ qmake-qt4 qt.pro $ make It seems this is a locking issue, a backtrace of when it is hung is below (gdb) back #0 0x21363d81 in __pthread_sigsuspend (set=0x6fbf7270) at ../linuxthreads/sysdeps/unix/sysv/linux/ia64/pt-sigsuspend.c:32 #1 0x21362380 in __pthread_wait_for_restart_signal (self=0x2137edc8) at pthread.c:1216 #2 0x2135d050 in __pthread_cond_wait (cond=0x60004338, mutex=0x600042e0) at restart.h:34 #3 0x2103f400 in QReadWriteLock::lockForWrite () from /usr/lib/libQtCore.so.4 #4 0x211d0340 in qt_addObject () from /usr/lib/libQtCore.so.4 #5 0x211d0e50 in QObject::QObject () from /usr/lib/libQtCore.so.4 #6 0x21184e20 in QFactoryLoader::QFactoryLoader () from /usr/lib/libQtCore.so.4 #7 0x2120b670 in QTextDecoder::~QTextDecoder () from /usr/lib/libQtCore.so.4 #8 0x21210ef0 in QTextCodec::codecForName () from /usr/lib/libQtCore.so.4 #9 0x2120c160 in QTextEncoder::fromUnicode () from /usr/lib/libQtCore.so.4 #10 0x2120efd0 in QTextCodec::codecForLocale () from /usr/lib/libQtCore.so.4 #11 0x210b30d0 in QString::toLocal8Bit () from /usr/lib/libQtCore.so.4 #12 0x210e04b0 in locale_encode () from /usr/lib/libQtCore.so.4 #13 0x210e06f0 in QFile::encodeName () from /usr/lib/libQtCore.so.4 #14 0x210f8e20 in QFileEngineHandler::QFileEngineHandler () from /usr/lib/libQtCore.so.4 #15 0x210e5460 in QFile::open () from /usr/lib/libQtCore.so.4 #16 0x40001070 in main () It seems that lock in qt_addObject has already been taken by something. Has anything changed in this area recently? BTW, using the libQtCore_debug.so.4 library didn't give me any useful line numbers or other debugging info. If you load it into gdb and run 'info functions' all the symbols are defined as non-debugging symbols.
