Gary Benson 992c7d700f Demangler crash handler ... This commit wraps calls to the demangler with a segmentation fault handler. The first time a segmentation fault is caught a core file is generated and the user is prompted to file a bug and offered the choice to exit or to continue their GDB session. A maintainence option is provided to allow the user to disable the crash handler if required. gdb/ 2014-06-19 Gary Benson <gbenson@redhat.com> * configure.ac [AC_CHECK_FUNCS] <sigaltstack>: New check. * configure: Regenerate. * config.in: Likewise. * main.c (signal.h): New include. (setup_alternate_signal_stack): New function. (captured_main): Call the above. * cp-support.c (signal.h): New include. (catch_demangler_crashes): New flag. (SIGJMP_BUF): New define. (SIGSETJMP): Likewise. (SIGLONGJMP): Likewise. (gdb_demangle_jmp_buf): New static global. (gdb_demangle_attempt_core_dump): Likewise. (gdb_demangle_signal_handler): New function. (gdb_demangle): If catch_demangler_crashes is set, install the above signal handler before calling bfd_demangle, and restore the original signal handler afterwards. Display the offending symbol and call demangler_warning the first time a segmentation fault is caught. (_initialize_cp_support): New maint set/show command. gdb/doc/ 2014-06-19 Gary Benson <gbenson@redhat.com> * gdb.texinfo (Maintenance Commands): Document new "maint set/show catch-demangler-crashes" option.		2014-06-19 09:13:57 +01:00
