Am I missing something, or is there still no reliable repro? I feel like gdb's reverse debugging support would be helpful here. I don't know how much time passes between the vector gets freed and when the symbol gets marked. I suspect it is the time between one GC and the next, which would be millions of instructions. Can reverse execution handle that? -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!
