Bug in tracing frames
[[[ To any NSA and FBI agents reading my email: please consider]]] [[[ whether defending the US Constitution against all enemies, ]]] [[[ foreign or domestic, requires you to follow Snowden's example. ]]] In gdb 7.01-debian, Emacs got into an infloop and I typed C-g C-g to get back to GDB. I got the following incomplete backtrace. Evidently GDB is unable to trace the stack back properly from the signal handler. This is on the Lemote Yeeloong.

Suggestion for `return'
The `return' command should set a flag so that `continue' behaves like `signal 0'. I know about the need for `signal 0' to avoid crashing, but just now I forgot it and lost important data. I think that anyone who takes the trouble to return out of a stack frame has indicated a desire to keep running the program rather than let it handle the signal. -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!

Bug in entering numbers
In GDB 7.0.1-debian print -2147483648 outputs $1 = 2147483648 which I think is not right. -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!

Re: Emacs .gdbinit incompatible with latest GDB
the recent GDB has problems running GDB `xbacktrace' on EMACS http://sources.redhat.com/ml/gdb/2007-02/msg00252.html It seems clear why the change was made: On the other hand byte arrays become unreadable if printed as strings. However, it seems that their hope this would not bother anyone was based on an assumption which is inaccurate: I hope nobody uses sign-specification for strings. Which GDB behavior is better is a matter of how often each one is convenient and how often it causes trouble. I don't know enough to have an opinion about that, but if neither one is clearly better overall, it would be best to leave GDB the way it was. ___ bug-gdb mailing list bug-gdb@gnu.org http://lists.gnu.org/mailman/listinfo/bug-gdb
