RE: [tcljava-user] Thread 2.5.2 on 64bit Solaris

[Rob R. <rr...@fu...>]

David,

I saw this problem on the Cray where the pointer length is 64 bit, but the pthread_t type is 32 bit. There is actually a
casting-related bug in the core Tcl thread library (Tcl_ThreadCreate) where it was assumed that both were the same size. The thread
id ends up being shifted to the left 4 bytes as a result.

The good news is that Zoran Vasiljevic checked in a fix into CVS. So just check out the head or the 8.4 branch for Tcl and that
should fix the problem.

Let me know if that doesn't work for you.

Rob
