SO, I started digging...
What I found is:
gperf/tests$ ../src/gperf -p -j1 -g -o -t -N is_reserved_word -k1,3,$ c-parse.gperf
[core dumped info]
ldah# gdb ../src/gperf gperf.core
[...]
Program terminated with signal 11, Segmentation fault.

As we can see above, delimiters are NULL, and they come NULL from
option (class Options), as because of [can't-see-any-reason] constructor
of Options class is not called (in constructor default delimiters are
set). Any idea why constructor may be not called???
In options.cc there'ss just 'Options option;'
Spec. delimiters to gperf (-e option) helps but not much.
Oh, btw, destructor is not called too.
