Such a watchpoint is never deleted due to it going out of scope. +* GDB now supports thread debugging of core dumps on GNU/Linux. + + GDB now activates thread debugging using the libthread_db library + when debugging GNU/Linux core dumps, similarly to when debugging + live processes. As a result, when debugging a core dump file, GDB + is now able to display pthread_t ids of threads. For example, "info + threads" shows the same output as when debugging the process when it + was live. In earlier releases, you'd see something like this: + + (gdb) info threads + * 1 LWP 6780 main () at main.c:10 + + While now you see this: + + (gdb) info threads + * 1 Thread 0x7f0f5712a700 (LWP 6780) main () at main.c:10 + + It is also now possible to inspect TLS variables when debugging core + dumps. + + When debugging a core dump generated on a machine other than the one + used to run GDB, you may need to point GDB at the correct + libthread_db library with the "set libthread-db-search-path" + command. See the user manual for more details on this command. + *** Changes in GDB 7.2 * Shared library support for remote targets by default |
