libxt xthreads support completely broken

[Reinhard Tartler]

ddd seems to trigger this bug. Already reported in malone:
https://launchpad.net/malone/bugs/2129

Steps to reproduce:
apt-get source hello
cd hello-*
./configure
make

ddd src/hello

backtracing with libxt-dbg gets me this:

#0 0xb7d6172e in _XtWaitForSomething (app=0x8350868, ignoreEvents=0,
ignoreTimers=1,
    ignoreInputs=1, ignoreSignals=1, block=Variable "block" is not available.
) at ../../src/NextEvent.c:194
194 ../../src/NextEvent.c: Datei oder Verzeichnis nicht gefunden.
        in ../../src/NextEvent.c

I think this is a segfault in libxt, can you confirm this?

awesome.

yeah, it is, probably related to the threading support. looks like it's quite
badly botched.

[Daniel Stone (daniels)]

okay, so I've just uploaded a version which should largely fix this. can't tell
at the moment whether the problem is lesstif or libxt.

I can confirm the problem and still encounter it. Downloading the lesstif source
package (0.93.94-11.4ubuntu2) and recompiling solved the problem for me. I guess
the lesstif package is no longer ABI compatible with the current libraries and
just needs a recompile against the current versions.

lesstif1-1 (1:0.93.94-11.4ubuntu3) breezy; urgency=low
  * rebuild for new libxt (Related to Ubuntu #14943)

Thanks, ddd now works again as expected.

[Reinhard Tartler (siretart)]

For me too. I'm closing this bug therefore. Thanks daniel!
