Good, so it's isql command that crashes:

make gpre
make[2]: Entering directory '/tmp/firebird-4.0.2/gen'
rm -f metadata.fdb
/tmp/firebird-4.0.2/gen/Release/firebird/bin/isql -q -i
/tmp/firebird-4.0.2/src/dbs/metadata.sql
make[2]: *** [Makefile:441: metadata.fdb] Segmentation fault (core dumped)
make[2]: *** Deleting file 'metadata.fdb'
make[2]: Leaving directory '/tmp/firebird-4.0.2/gen'
make[1]: *** [Makefile:292: master_process] Error 2

And my question is, how run it under gdb?=
