I have just installed the same 32bit ActiveState Windows version on Windows XP and TCL will also crash at [package req XOTcl]. So, this might be related to the specific build of ActiveState binary. ----- Original Message ----- From: "Gustaf Neumann" <neumann(a)wu-wien.ac.at> To: xotcl(a)alice.wu-wien.ac.at Sent: Thursday, October 14, 2010 12:29:00 AM GMT -08:00 US/Canada Pacific Subject: Re: [Xotcl] troubleshooting 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? -gustaf neumann On 14.10.10 08:21, Victor Mayevski wrote: > Thank you Gustaf, > I am using the ActiveState binary and XOTcl is version 1.6.6, not NX.
