>Description:
Running "sudo" or "visudo" from a freshly-built pkgsrc/security/sudo reliably crashes.  This does not seem to apply to all natively built binaries, as digest and gnu m4 were successfully used to build the sudo package.

Classified as a toolchain problem because it seems to be croaking when processing global constructors:

cobalt:thorpej 15$ visudo
