[Ecls-list] Freeze import.c which is threads examples source

[zqwell]

Hello everyone.

I have ECL (ver 1.4.1) which was compiled with
"./configure --enable-threads --enable-boehm --enable-unicode" on Mac
OS X 10.6.3.

I want to use multi-thread, so I tried to run threads examples
(source path is /examples/threads/import/import.c).

But freeze it with the following output console.
-----------------------------------------------
macbook:~/ecl_1.4.1/examples/threads/import$ ./import.exe

0
1
-----------------------------------------------

I use gdb backtrace for specifying where to freeze.

The following is backtrace.
-----------------------------------------------
macbook:~/ecl_1.4.1/examples/threads/import$ gdb -q ./import.exe
Reading symbols for shared libraries .
...(omission)...
(gdb) r

-----------------------------------------------

I cannot understand why freeze it.
please tell me your advice for doing correctly.
