Is Tcl broken in B20.1 ?


Hi,

I try to run very small thing under the CYGWIN B20.1

source file:
--------------------------------------------
#include <tcl.h>

main()
{
    Tcl_Interp *t = Tcl_CreateInterp();
}
--------------------------------------------

compilation:
    gcc -g -o t t.c -ltcl80

--------------------------------------------
run:
 <47> ./t
[main] C:\alexr\G++\t.exe 1120 (0) handle_exceptions: Exception:
STATUS_ACCESS_VIOLATION
[main] t 1120 (0) handle_exceptions: Dumping stack trace to t.exe.core

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

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

This worked very well in B19. Am I wrong in something?
