That was before I read this e-mail. I will give the version number below first and see if I can run valgrind to obtain the redirection information. (The thing is the already running valgrind+thunderbird is stretching my 16GB memory linux image and I am not sure if I can start another instance of valgrind+thunderbird, or I need to bite the bullet and cancel the current run. I am afraid that the test takes close to a full day...) Anyway, let me first send this version info, and I will check to see if I can obtain the redirection info easily. Obviously, I don't seem to have the redirected symbol for strncpy in the trace. That is for sure. I do see redirection for malloc. 279:13.66 GECKO(392456) ==392459== at 0x483F7B5: malloc (vg_replace_malloc.c:381) --- version info --- Hi, Before I can figure out how to create a short reproducer, here is the version info I collected.
