Hi, all.<br>I've a problem of _Thread_Disable_dispatch() function in below code. It's my implementation of _POSIX_Keys_Run_destructors() function. I come across the problem when I run the psxkey03 test:if _Thread_Disable_dispatch() was commented out, psxkey03 can run without problem. when _Thread_Disable_dispatch() added at line 1(as below), psxkey03 will fail. I debug it in sparc-rtems4.11-gdb, and find psxkey03 runs into _Internal_error_Occurred() function then stop. I know _POSIX_Keys_Get()(at line 12) will also disable thread dispatch--does this lead to the problem? However, can't figure out where exactly the problem exists, could anyone explain it? Thanks!<br>
