gdb

I am learning gdb to debug the program. As soon as I run the program,
it prompt me an error and terminated.
How to step into it or set breakpoint and find the problem. Thanks.

(gdb) run
Starting program: /usr/home/grp/gramtest < inputdata
terminate called after throwing an instance of 'std::logic_error'
what(): empty rule

<shrug> You're asking a tool question in a language newsgroup. You
are off-topic. Try gnu.tools.help.

Wrong group. Try gnu.g++.help.

This group is for the discussion of the C++ language as defined by
ISO/IEC 14882:2003. How to use your specific toolset is offtopic.

gdb is off-topic here, you should try some gcc group or read gdb manual.
There are also graphic front-ends for gdb which ought to be easier to use.

I just mention how to put a breakpoint on exception throwing in gdb as this
is really obscure: b __cxa_throw

Google for "gdb tutorial" and select any of the first hits, RMS's is
quite good.
