Your first bug report is very good. Thank you.
But it is not real bug. Issue is that you call your function `write',
which is collision with normal write(2) function.
In this situation I would expect linker error, but what actually happens
is that your function shadows write(2) one. Problem is that `gdbm_open'
internally uses write(2), so here we have endless rescursion.
If you have little available descriptors, result will be as you described.
If you have many available described, result will be stack overflow and
segfault. It happens on my system.
Try renaming your `write' function into `my_own_write' and check again.
Closing bug for now. Feel free to reopen it, if `my_own_write' would still
misbehave.

BTW, main function must return something, otherwise exit code is
undefined.
