Hi, before digging deeper please try the latest version 3.27.6.7 which was commited now. I tried 3.27.6.7 on a main-n257645 kernel and it still core-dumps.
Here is the tail end of ktrace(8) output:

Hi, I don't have a /usr/local/share/qcad/plugins/script/qt either nor a shortdump. What does ldd /usr/local/share/qcad/plugins/script/libqtscript_core.so.1.0.0 show? Maybe a missing dependency? Created attachment 236229 [details]
LDD on qcad binary
ldd looks good, see attachment. Tried running with lldb, but it's probably not much help:

FWIW this started happening after commit 787e501e3d8fdc162dc019f352b280298b192b0a Author: Tobias C. Berner <tcberner@FreeBSD.org> Date: Tue Jun 28 10:08:18 2022 +0200 qt5: Update Qt to 5.15.5 (KDE patched) - update patch-collection diff to be at the highest patch-level - update patch-collection diff to be against 5.15.5 instead of 5.15.2 - update devel/qt5-script to 5.15.10 - libressl support by Felix Palmen <felix@palmen-it.de> The curious things is if you compile devel/qt5-script (or was it qt5-scripttools? qt5-script, I think) with debug, the problem seems to go away. I don't remember if I tried rolling back qt5-script itself to the previous one, then again there doesn't seem to be an actual difference between 5.15.2p4 and 5.15.10p0, files/ hadn't changed in ages either (and I gave up looking here). Oh, I'm on 13.1-RELEASE-p1. This might be a more general problem with qt5-script or some other parts of Qt though (that is likely to have started with 787e501e). I have just tested databases/sqlitestudio and emulators/ukncbtl, which both make use of Qt's scripting facilities (fair warning though, I am not a regular user of these packages). As soon as either is triggered to run a QtScript/JavaScript/whatever it is called today script/function, a crash occurs in libQt5Script.so (which had been compiled without debug, as having it compiled with debug seemingly makes the entire problem go away). On the other hand, were this completely true, one would assume large chunks of KDE to be failing as well, but there doesn't seem to be any obvious noise in that neck of the woods, so take this observation for what it's worth.

() Backtrace stopped: Cannot access memory at address 0x7fffdf7fa000 Just tried, qcad also coredumps on 13.1-R (In reply to Poul-Henning Kamp from comment #9) Hi Poul-Henning, If you just need to use qcad then, as somebody mentioned above, the workaround is to install devel/qt5-script with debug info (WITH_DEBUG=yes). Yuri Hi, just updated qcad to 3.27.7.0 Maybe it does help? (In reply to Michael Reifenberger from comment #11) QCAD version 3.27.7 19:06:19: Debug: loading plugins... 19:06:19: Debug: loading static plugins... Segmentation fault not better on 13.1, I have core dumps disabled, but same seg fault I am using binary package on FreeBSD 13.1-RELEASE (pkg install) and I have the same problem still. Thank you. Apparently what helps here isn't the debug itself, rather disabling the optimizations, so building qt5-script with e.g. CFLAGS="-pipe" helps as well (could be a "fix" here?).
Anyway, here's a bit better backtrace, qt5-script built with -O2 (so that qcad dumps core), -g, and not stripped (STRIP=""):

disable optimizations
The following patch seems to help...
See bug #277236 for a seemingly proper fix that works for me Yes disabling optimization for devel/qt5-script does prevent the dump. So in the end it seems a devel/qt5-script issue. |
