 I just noticed that the error message also appears when running the 
 lib/libc/gen/posix_spawn/t_spawn tests:

 Grepping for the error message in the log files from the automated
 test runs on babylon5.netbsd.org, I found that the first time the
 message appared was in
 
   http://releng.netbsd.org/b5reports/i386/build/2015.05.23.18.13.31/test.log
 
 which means the bug was introduced by the following commit by maxv:
 
    2015.05.23.18.13.31 maxv src/sys/arch/i386/conf/GENERIC 1.1125
    2015.05.23.18.13.31 maxv src/sys/arch/i386/conf/XEN3_DOM0 1.95
    2015.05.23.18.13.31 maxv src/sys/arch/i386/conf/XEN3_DOMU 1.67
 
 with the commit message:
 
    Disable COMPAT_FREEBSD. The implementation is poor, not well tested and
    almost irrelevant. People who need it (for tw_cli for example) can still
    recompile their kernels with this option.
