drh f45c695471 Reinstant the work-around for [https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96270|GCC compiler bug 96270]
which is apparently still an issue as of gcc 13.3.0 with -m32 on Mint Linux.
The test case in the bug report is fixed, but the vdbeMemRenderNum() routine
in SQLite still shows the problem.
