Hi,
In the GNU Bison manual at '3.6.1 Data Type of Locations'
When YYLTYPE is not defined, Bison uses a default structure
type with four members:
typedef struct YYLTYPE
{
int first_line;
int first_column;
int last_line;
int last_column;
} YYLTYPE;
But a signed int will start overflow at 2147483647
(2G) number of input lines in the input.
Is this correct and because of POSIX definition ?
Nowadays on 64-bits GNU/Linux machines with big files
this looks like a 32-bits limit in Bison Yacc/GLR
default generated output parsercode.
Maybe the manual can mention the user must add own
macro YYLTYPE with bigger data types for full
64-bits on current 64-bits GNU/Linux machines if
needed when parsing big files.
Checked the generated parser code and for debug
output only own definintion of YY_LOCATION_PRINT
to add at changes, thats all.
Thanks,
Tys.
