It does not crash for me.

Are you running nscd or unscd?

Stock 12.2 and Factory installs, unscd is installed but not running which seems to be the default. Segfaults every time on my quadcore, in a single-cpu kvm guest it's more difficult to reproduce but still occasionally segfaults as well. Try running it in a loop for a while: while ./atest; do :; done -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Start nscd/unscd - does it still fail for you?

It only crashes for me if I stop nscd but works fine if nscd runs.

I've only done a quick check, but I haven't been able to reproduce the segfaults with nscd running. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Another reason was that thread-enabled extensions work fine with a non-threaded Tcl core, but not the other way around. As threads aren't that popular in the Tcl world (because it has a very good event model that works much better in many cases where threads are used in other languages), I didn't want to affect the majority of Tcl users with the (IIRC) 5..10% performance hit that enabling threads induces. With 8.6 (which is at most a couple weeks from being released, from what I can tell) performance has been improved all over the place, so that thread-enabled 8.6 won't be slower than 8.5 without threads. That's why upstream changes the default. And with 8.6 being so close, I really don't want to flip the threads switch for 8.5, after it has been off undisputed for so many years. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

BTW, is there no way to tell TclCurl not to use threads, even if libcurl was built with threads support?

Unfortunately using the libcurl multi interface there is no way to influence internal thread usage, it's an implementation detail that isn't even documented in curl AFAICT. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The next openSUSE release will ship with Tcl 8.6 which has threads enabled by default.

I still would like to fix this for 12.2/12.3. How about forcibly building tcl against libpthread, that is not by enabling threads support but by simply putting "-pthread" into CFLAGS? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Packages for 12.2 and 12.3 are now in home:rmax:branches:OBS_Maintained:tcl . Please test.

Thanks. But shouldn't generally -pthread be used instead of -lpthread since the former also makes sure thread-safe glibc functions and data structures are used?
