and size overflow errors. * data/glr.c: Include <stdio.h> etc. after user prolog, not before, in case the user prolog sets feature-test macros like _GNU_SOURCE. (YYSIZEMAX): New macro. (yystpcpy): New function, taken from yacc.c. (struct yyGLRStack.yyspaceLeft): Now size_t, not int. (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls, so that we don't have to maintain their signatures. (yyFail): Check for buffer overflow, by using vsnprintf rather than vsprintf. Allocate a bigger buffer if possible. Report an error if buffer allocation fails. (yyStackOverflow): New function. (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether the initialization was successful. It might fail if storage was exhausted. (yyexpandGLRStack): Add more checks for storage allocation failure. Use yyStackOverflow to report failures. (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction): (yysplitStack, yyprocessOneStack, yyparse, yypstack): Don't assume stack number fits in int. (yysplitStack): Check for storage allocation failure. (yysplitStack, yyprocessOneStack): Add pure_formals, so that we can print diagnostics on storage allocation failure. All callers changed. (yyresolveValue): Use yybool for boolean. (yyreportSyntaxError): Check for size-calculation overflow. This code is taken from yacc.c. (yyparse): Check for storage allocation errors when allocating the initial stack.
This directory contains the Bison parser generator. See the file INSTALL for generic compilation and installation instructions. See the file doc/FAQ for frequently asked questions. Bison requires GNU m4 1.4.3 or later. See: ftp://ftp.gnu.org/gnu/m4/m4-1.4.3.tar.gz Bison can work with pre-1.4.3 distributions of GNU m4 if they are sufficiently patched, but if you encounter a bug with an older distribution and report a bug we will probably suggest that you upgrade to 1.4.3 as the first step in trying to fix it. Please send bug reports to <bug-bison@gnu.org>. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report. If you have questions about using Bison and the documentation does not answer them, please send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004, 2005 Free Software Foundation, Inc.
