Dear Victor,
many thanks for the short example! i have compiled xotcl 1.6.6 with my three test releases, the script runs fine in every version, also valgrind did not report unusual happenings, but i tried so far only with mac os x with 64bit.
i am slightly confused about the activestate version number TCL 8.6.0.0b4. There was never a version of Tcl 8.6 b4 released (or tagged on sourceforge). As you wrote, the tcl_patchLevel is 8.6b1.2, which is the current HEAD release (and therefore a moving target). Apparently, activestate uses its own tags. Have you seen somewhere on activestate a source-release?

Thank you Gustaf, I am using the ActiveState binary and XOTcl is version 1.6.6, not NX. I don't know where to get the source code for TCL 8.6.0.0b4, it is not available anywhere yet.
I think I have zeroed in where the crash happens. Here is the sample code that causes the crash for me:
tcl_patchLevel 8.6b1.2 tcl_platform(byteOrder) = littleEndian tcl_platform(machine) = x86_64 tcl_platform(os) = Linux tcl_platform(osVersion) = 2.6.35-22-generic tcl_platform(pathSeparator) = : tcl_platform(platform) = unix tcl_platform(pointerSize) = 4 tcl_platform(threaded) = 1 tcl_platform(user) = root tcl_platform(wordSize) = 4

I have also installed the 32bit version of the same ActiveState binary (the latest one, 8.6.0.0b4, tcl_patchLevel 8.6b1.2) and it will crash right at [package req XOTcl]
Hope that helps

Hi Victor,
our typical test setup is to run the regression test with 8.5.9, tcl 8.6b1, and with 8.6head version (where i have applied the SANE-NRE-patch from Miguel). i just double-checked, for me all three test settings work fine.
does the regression work on your installation with tcl 8.6b4 (run: make test)? If they run fine, and you experience a crash with your application, the following works probably best:
Strategy a: try to isolate and pinpoint the problem from the tcl layer by simplifying your script. if the problem can be reproduced with a few lines of code, send it to me.
Strategy b: mostly for c-literate developers: use gdb.
- compile tcl and nsf with -g enabled (e.g. add it to the compile flags in the Makefile and recompile with "make clean" and "make") - start the tcl shell under gdb, like e.g. gdb /usr/local/src/tcl8.5.9/unix/tclsh - start your application from gdb using run ..../yourapp.tcl - when it crashes, type in where an you will get the backtrace. maybe what you see makes sense to you. if not, send it to me, i'll try me best on it.all the best -gustaf

I have just tried my application on latest TCL 8.6b4 and it crashes (Segmentation fault). The same application works just fine in TCL 8.5.9. Any idea how I can troubleshoot it? Tools, techniques etc?
