When using libthr (mapped from libpthread via libmap.conf) on FreeBSD 6.1-RELEASE, I can't run any Qt applications from gdb. Any application I ru= n reports: Program received signal SIGFPE, Arithmetic exception. [Switching to Thread 0x8c93000 (LWP 100120)] 0x2915ddb7 in QLocalePrivate::stringToDouble () from /usr/X11R6/lib/libqt- mt.so.3 (gdb) bt #0 0x2915ddb7 in QLocalePrivate::stringToDouble () from /usr/X11R6/lib/libqt-mt.so.3 #1 0x2917308c in QString::toDouble () from /usr/X11R6/lib/libqt-mt.so.3 #2 0x28e8967b in QFont::fromString () from /usr/X11R6/lib/libqt-mt.so.3 #3 0x28e0d712 in QApplication::x11_apply_settings () from /usr/X11R6/lib/libqt-mt.so.3 #4 0x28e0e63e in qt_set_x11_resources () from /usr/X11R6/lib/libqt-mt.so.3 #5 0x28e126fe in qt_init_internal () from /usr/X11R6/lib/libqt-mt.so.3 #6 0x28e14bac in qt_init () from /usr/X11R6/lib/libqt-mt.so.3 #7 0x28e74231 in QApplication::construct () from /usr/X11R6/lib/libqt- mt.so.3 #8 0x28e7465c in QApplication::QApplication () from /usr/X11R6/lib/libqt- mt.so.3 The applications run fine outside of gdb or when switching back to libpthread. Is this a known problem? If so, is there also a known solution? :) Best regards, Arjan van Leeuwen
