1. Patched & installed libthr r302195
2. test for other soft:
mousepad
GLib (gthread-posix.c): Unexpected error from C library during
'pthread_mutex_trylock': Уникнуто взаємне блокування ресурсів.
Aborting. Аварійне завершення(записано core)
3.test new ./thr_mutex_test
thr_mutex_test: mutex_trylock 2: No error: 0
4. restore patch & install original libthr r302195
5. test for other soft:
mousepad
GLib (gthread-posix.c): Unexpected error from C library during
'pthread_mutex_trylock': Уникнуто взаємне блокування ресурсів.
Aborting. Аварійне завершення(записано core)
6. test new ./thr_mutex_test
thr_mutex_test: mutex_trylock 2: No error: 0
7. restore & install libthr r302191
8. test for other soft:
mousepad - complete run
9. test new ./thr_mutex_test
thr_mutex_test: mutex_trylock 2: No error: 0
