https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258392 Bug ID: 258392 Summary: lang/tcl85 lang/tcl86: fix unsafe buffer lifetime Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: Individual Port(s) Assignee: tcltk@FreeBSD.org Reporter: dim@FreeBSD.org Assignee: tcltk@FreeBSD.org Flags: maintainer-feedback?(tcltk@FreeBSD.org) Created attachment 227791 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D227791&action= =3Dedit lang/tcl8[56]: apply upstream fix for unsafe buffer lifetime During an exp-run for llvm 13 (see bug 258209), it turned out that lang/tcl8[56] compiled with clang 13 result in problems when databases/sqli= te3 attempts to generate its main sqlite3.c source with tclsh [1] [2]: sqlite3.c:17852:2: error: invalid preprocessing directive #defi 0, xStep,xFinal,xValue,xInverse,#zName, {0}} ^ sqlite3.c:18129:2: error: invalid preprocessing directive #definly system table */ ^ sqlite3.c:18223:2: error: invalid preprocessing directive #defi /* ON DELETE and ON UPDATE actions, respectively */ ^ After some searching in tcl history I found that the cause is upstream tick= et https://core.tcl-lang.org/tcl/info/24b9181478 ("Fix unsafe buffer lifetime"= ). They patched the 8.5 and 8.6 branches, but this didn't appear in a release = yet. 8.7 already has the fix. The unsafe buffer gets optimized differently with clang 13, causing the sql= ite3 build to break due to its tcl scripts outputting garbled generated code. Here is a patch for tcl 8.5 and tcl 8.6. I verified that all tcl versions in the ports tree can now be compiled with clang 13, and then succesfully gene= rate the sqlite3.c main file.
