[Bug 1341125] Re: Cannot enter floating point (double) numbers

[Fabrizio Gennari]

Sorry, but I can still reproduce it.

Precondition is that gdb is built with Python 3 support (and the one
distributed with Ubuntu 14.10 is) and the current locale has a comma as
decimal separator (I am using it_IT.UTF-8).

At startup, gdb executes _initialize_python () (in file
python/python.c): the following lines of code changhe the locale from C
(which is the appropriate one, since gdb must be able to parse numbers
that are valid in C language) to the one of the machine

1651	  progname = concat (ldirname (python_libdir), SLASH_STRING, "bin",
1652			     SLASH_STRING, "python", NULL);
1653	#ifdef IS_PY3K
1654	  oldloc = setlocale (LC_ALL, NULL);
1655	  setlocale (LC_ALL, "");

>From this point on, gdb assumes that the decimal separator is a comma,
and becomes unable to parse the number 1.0
