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. #0 0x12000dbc8 in strcspn1 (s=0x12002e168 "__alignof, ALIGNOF, NORID", reject=0x0) at ./key-list.cc:162 162 for (scan = s; *scan; scan++) (gdb) bt #0 0x12000dbc8 in strcspn1 (s=0x12002e168 "__alignof, ALIGNOF, NORID", reject=0x0) at ./key-list.cc:162 #1 0x1200069f4 in parse_line (line=0x12002e168 "__alignof, ALIGNOF, NORID",delimiters=0x0) at ./key-list.cc:335 #2 0x120006e20 in Key_List::read_keys (this=0x11ffba10) at ./key-list.cc:376 #3 0x120004058 in Gen_Perf::Gen_Perf (this=0x11ffba10) at ./gen-perf.cc:39 #4 0x120003dec in main (argc=10, argv=0x11ffbae8) at ./main.cc:62 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. greetings marcin -- .d$$$$b, $d$$$$b. .d$$$$b, Marcin Gryszkalis <dagoon@math.uni.lodz.pl> $$' `"" $$' `"' $$' `$$ $$. .ss $$ $$ $$ (...) QED.
