--- Begin Message ---Package: tclex Version: 1.2a1-14 When I try to run transcriber, which uses tcLex, under a version 8.5 Tcl/Tk wish, it segfaults. If a file is specified on the command line, it crashes immediately; otherwise it opens a file chooser and then crashes after you choose a file. (I suspect that this is the same failure behind transcriber bug #484738, though it's hard to be sure because there aren't any details of the failure in that report.) Here's the tcLex part of the stack backtrace: #0 0xb6dfc722 in RuleGetRange (interp=0x8053f80, lexer=0x8358ff8, rule=0x82d34f8, stringObj=0x88cab00, index=0, rangeIndex=0, startPtr=0xbfd21880, endPtr=0xbfd2187c) at RE82.c:140 #1 0xb6dfa779 in RuleTry (interp=0x8053f80, lexer=0x8358ff8, iRule=0, bCheckOverrun=0, pMinLength=0xbfd218d4) at tcLex.c:1580 #2 0xb6dfad3c in LexerEval (interp=0x8053f80, lexer=0x8358ff8, bCheckOverrun=0) at tcLex.c:1859 #3 0xb6dfb5fc in LexerEvalObjCmd (interp=0x8053f80, lexer=0x8358ff8, objc=4, objv=0x816c8c4, op=0) at tcLex.c:2193 #4 0xb6dfc23b in LexerObjCmd (clientData=0x8358ff8, interp=0x8053f80, objc=4, objv=0x816c8c4) at tcLex.c:2950 #5 0xb7cdb741 in TclEvalObjvInternal (interp=0x8053f80, objc=4, objv=0x816c8c4, command=0xffffffff <Address 0xffffffff out of bounds>, length=-1, flags=0) (My invocation to get this to run under GDB with debugging symbols is: LD_LIBRARY_PATH=/src/debian/tclex-1.2a1/install/lib:/src/debian/tcl8.5-8.5.2/install/lib TCLLIBPATH=/src/debian/tclex-1.2a1/install/lib/tcltk gdb --args /src/debian/tk8.5-8.5.2/unix/wish /usr/lib/transcriber1.5/tcl/Main.tcl /tmp/foo.wav where I've done source builds of the respective tcl8.5, tk8.5, and tclex packages with debugging enabled) Line 140 is: *startPtr = regexpPtr->matches[rangeIndex].rm_so+index; and the proximate cause of the segfault is that regexpPtr->matches is null. I tried adding an extra guard condition of "|| !regexpPtr->matches" on the preceding if statement, and that prevents the segfault, but it seems to give the wrong behavior. It causes transcriber to die with a parse error on a file that should be known to be correct. (The XML DTD describing its file format.) Looking back at the package history, it appears that tcLex has needed a bit of porting for every time the Tcl regexp library is updated, so I think that's what's called for again. But it still works fine for me with Tcl 8.4, so a fallback would be detect the incompatibility and give a better error. Relevant package versions: ii tcl8.5 8.5.2-1 Tcl (the Tool Command Language) v8.5 - run-t ii tk8.5 8.5.2-1 Tk toolkit for Tcl and X11, v8.5 - run-time ii transcriber 1.5.1.1-1 Transcribe speech data using an integrated e -- Stephen
