I don't have any sid machines right now to try this on, but I grabbed the updated mutt-patched source and built it on my wheezy setup using dpkg-buildpackage. Everything went fine but I still get the segfault with the updated package. The only info I've got to add at this point is what showed up in my dmesg: [ 6340.496717] traps: mutt[12627] general protection ip:29cc5c6f0d5 sp:3b3172ecc80 error:0 in libc-2.13.so[29cc5bf8000+182000] [ 6340.496737] grsec: Segmentation fault occurred at (nil) in /usr/bin/mutt-patched[mutt:12627] uid/euid:1000/1000 gid/egid:1000/1000, parent /bin/mksh[ksh:6561] uid/euid:1000/1000 gid/egid:1000/1000 [ 6340.496753] grsec: denied resource overstep by requesting 4096 for RLIMIT_CORE against limit 0 for /usr/bin/mutt-patched[mutt:12627] uid/euid:1000/1000 gid/egid:1000/1000, parent /bin/mksh[ksh:6561] uid/euid:1000/1000 gid/egid:1000/1000 but that's not all that helpful. If I get a chance, I'll try to capture more debug information or try to reproduce the problem with gdb attached again. Thanks for the update, though. -- -Joe MacDonald. :wq
