When I am trying to set the break point on a constructor of a
templated class (two vector type template parameters), and I use TAB
TAB to get the completion list in the *Completions* buffer (under
emacs) and then mouse-2 or RETURN to select the desired constructor,
I get this pasted into my gdb session:
(gdb) break 'TxDataModelFunctor<vector<double, allocator<double> >,
vector<double, allocator<double> >
>::TxDataModelFunctor(vector<double, allocator<double> > const &,
vector<double, allocator<double> > const &,
TxParametricModel<vector<double, allocator<double> >, vector<double,
allocator<double> > > *)
After adding the closing single quote, I get the error:
malformed template specification in command
If I do a simmple query replace in a temporary buffer to substitute:
from: vector<double, allocator<double> >
to: vec_t
the result looks ok to me:
break 'TxDataModelFunctor<vec_t, vec_t >::TxDataModelFunctor(vec_t
const &, vec_t const &, TxParametricModel<vec_t, vec_t > *)
I assume this is a bug because I am using the syntax provided to me by
GDB and the program compiles.
Thanks,

version info:
gdb 5.0 under emacs 20.5.1. The program I am debugging was
compiled with 'g++ --ggdb' using gcc-2.95.2.
Here is the header file for the TxDataModelFunctor. The template
parameters RetVecType and ArgVecType were both instantiated with
vector<double>.
