Package: swig Version: 1.3.24-1 Severity: important When wrapping C++ for use from Python, qan expression of the form "using ::baz;" sends Swig_symbol_clookup into an infinite recursion that ends with a segfault when the stack is exhausted. This makes it pretty much unusable on a our code. Swig 1.3.22 didn't have this problem.
I've built a debugging version from the apt sources. Given a file demo.i as follows: ------------------------------------------------------------ %module demo using ::baz; ------------------------------------------------------------ ...running swig with the following arguments: -v -c++ -python demo.i ...generates the following a stack trace (with the leading 990 or so Swig_symbol_clookup frames elided for brevity:) ------------------------------------------------------------ #990 0x080ded3f in Swig_symbol_clookup (name=0x4032ff98, n=0x4023e178) at Swig/symbol.c:897 #991 0x080ded3f in Swig_symbol_clookup (name=0x4032ff98, n=0x4023e178) at Swig/symbol.c:897 #992 0x080ded3f in Swig_symbol_clookup (name=0x4032ff98, n=0x4023e178) at Swig/symbol.c:897 #993 0x080ded3f in Swig_symbol_clookup (name=0x4032ff98, n=0x4023e178) at Swig/symbol.c:897 #994 0x080ca603 in TypePass::usingDeclaration (this=0x4032ff98, n=0x4032ffa8) at Modules/typepass.cxx:820 #995 0x08087daa in Dispatcher::emit_one (this=0xbffff960, n=0x4032ffa8) at Modules/lang.cxx:133 #996 0x08087f72 in Dispatcher::emit_children (this=0xbffff960, n=0x4032ffa8) at Modules/lang.cxx:206 #997 0x080c89e8 in TypePass::includeDirective (this=0x65000000, n=0x4032ff98) at Modules/typepass.cxx:329 #998 0x08087ca6 in Dispatcher::emit_one (this=0xbffff960, n=0x4032fef8) at Modules/lang.cxx:159 #999 0x08087f72 in Dispatcher::emit_children (this=0xbffff960, n=0x4032fef8) at Modules/lang.cxx:206 #1000 0x080c86f5 in Swig_process_types (n=0x402400b8) at Modules/typepass.cxx:290 #1001 0x08090424 in SWIG_main (argc=5, argv=0xbffffce4, l=0x4032ff98) at Modules/main.cxx:805 #1002 0x080c487c in main (margc=1694498816, margv=0x65000000) at Modules/swigmain.cxx:195 ------------------------------------------------------------ -- System Information: Debian Release: 3.1 APT prefers testing APT policy: (800, 'testing'), (1, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.8-2-686 Locale: LANG=en_US, LC_CTYPE=en_US (charmap=ISO-8859-1) Versions of packages swig depends on: ii libc6 2.3.2.ds1-20 GNU C Library: Shared libraries an ii libgcc1 1:3.4.3-9 GCC support library ii libstdc++5 1:3.3.5-9 The GNU Standard C++ Library v3 ii libswig1.3.22 1.3.22-5 Runtime support libraries for swig -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
