Subject: Re: uisimulator segfaults on winnt 4.0
it bangs before main!
I have no clue about debugging, but i was digging the net and found some
infos - so i set another
breakpoint at mainCRTStartup, as this was suggested somewhere.
this is what I get:
$ gdb uisw32.exe

(gdb) break mainCRTStartup
Breakpoint 1 at 0x401006
(gdb) break main
Breakpoint 2 at 0x419ffa: file ../../firmware/drivers/lcd-recorder.c, line
Starting program: /home/rockbox/build/uisw32.exe
Breakpoint 1, 0x00401006 in mainCRTStartup ()
Program received signal SIGSEGV, Segmentation fault.
0x00000024 in ?? ()
#0 0x00000024 in ?? ()
Cannot access memory at address 0x17100fe
So it seems to crash somewhere between mainCRTStartup()? (eeerrrr - what is
that?) and main(). What is executed before main() ?
Whatelse can I do ? I`m happily if I can learn something about debugging....
