Note that gdb does not detect the problem w/ the core that adb does.
It's possible that the core is truncated for quota reasons:
[bobbi-harlow!jhawk] ~> ls -l core
-rw-r--r-- 1 jhawk mit 124876 Jun 16 03:35 core
[bobbi-harlow!jhawk] ~> fs lq
Volume Name Quota Used % Used Partition
user.jhawk 12500 12577 101%<< 85% <<WARNING
Moving the core aside, the problem is not replicable:
[bobbi-harlow!jhawk] ~> mv core /var/tmp/core.jhawk
[bobbi-harlow!jhawk] ~> man strerror
strerror(3C) C Library Functions strerror(3C)
...
I've placed a copy of the core in /mit/coredumps/jhawk/apropos.814.core.
