I have build Vim 7.2 with BeOS GUI on Haiku. Current version of BeOS

struct stat stat_stdin, stat_dev_null;

stat("/dev/null", &stat_dev_null) == -1 ||

But this doesn't work with Haiku.
This code works fine under Haiku, I just tested it.
Are you sure you haven't changed your Bootscript and redirected its
output to /dev/dprintf or something like that?
Ups... Looks like I was wrong. Sorry, folks! Just tested this code again
with extra tracing and it works. :-( The problem is something elsewhere
- all I have found - some lines in the syslog during attempt to start
vim from Tracker:
KERN: vm_soft_fault: va 0x0 not covered by area in address space
KERN: vm_page_fault: vm_soft_fault returned error 'Bad address' on fault

Looks like it silently crashed during start - no vim windows displayed.
I wonder why it doesn't catched by gdb as usual access violations in
user programs? Are there any tricks to start it under gdb in the same
way as from Tracker? Thank you.
Kind Regard,
S.Zharski
