high load MySQL server could crash if two or more threads would initiate query cache resize at the moments very close in time. The problem was introduced with the fix of bug 21051 in 5.0 and 5.1: simultaneous query cache resizes would wait for the first one in progress, but then each thread would try to finish the operation, accessing the data that was already reset (attempt to dereference 'bins' pointer, which may be NULL already). The solution is to check after synchronization if another thread has done the reset already (test 'query_cache_size > 0' again). No test case is provided because the bug is a subject to a race.

The build scripts in general, using automake, autoconf, etc, contain several special commands and work around all related to the way the bison code in the parser is built, for sql/sql_yacc.yy. These work arounds, accumulated over time during development, ultimately cause the build scripts to be unstable and cause build defects by not enforcing dependencies. This fix simplifies the build process and aligns it with the automake tooling, which provides native support for bison and *.yy files. In particular, the following problem have been fixed: - dependencies with sql_yacc.cc were not honored (Bug 21029), leading to corrupted builds, - the work around introduced by Bug 24557, to cleanup the generated files sql_yacc.h and sql_yacc.cc, has been removed, - the generated makefile, in a source distribution, used to destroy the files sql_yacc.h and sql_yacc.cc on a 'make clean' target. This has been fixed: these files are now removed by make maintainer-clean. - The root cause of the problem found with gcc 4.1 (see Bug 24619) has been clearly documented, and the "sed" hack has been replaced by a cleaner work around, when building the code with bison 1.875. - Removed the file sql/sql_yacc.yy.bak, added by WL 3031 by accident. - Removed the unnecessary AM_YFLAG= --debug introduced by WL 3432, since the compiling option DBUG_OFF takes precedence when setting YYDEBUG.

Fixed test. On 32-bit machines which compile without -DBIG_TABLES, MAX_ROWS is truncated to a 32-bit value. Using a value below 4G is portable.
