Description Pietro Cerutti freebsd_committer freebsd_triage 2011-02-03 11:20:07 UTC 
A missing declaration of void *cgdb_malloc(size_t) makes the compiler assume that the function return int, thus truncating the returned 64-bit pointer to 32 bits.
This causes the returned malloc'd pointer to point to an invalid location, thus causing the seg-fault. This has been discussed with one of the authors on IRC, a fix will be included in the next version upstream. I think it is important nonetheless to include a patch immediately to prevent systematic segfaults on amd64.

Fix: Add this patch.

Patch attached with submission follows:
How-To-Repeat: Run cgdb on amd64.
