Last night, I updated the mutt package on my NetBSD/alpha system from 
1.4.1 to 1.4.2, and now it dumps core :(

pid 8683 (mutt): unaligned access: va=0x1ffffeb14 pc=0x1603d4670

Anyone else having problems?

The system is running -current with userland from Jan 21 and kernel from 
Jan 24; perhaps I should try updating both (libc, in particular), but it 
doesn't look like wcrtomb() has had any changes in a while.
