Today I wanted to code some string functions for my os and changes also a little bit my code, but as I wanted to compile my code I got this error! I can still compile small files. The problem is, why are 800MB free RAM not enough?

did you try to change the memory size in Options > Compiler setup menu?

You have to show the source that causes the problem.

I will see when I can load it up, because it is a little bit big (109KiB)!

commandline also has -m switch to specify memory settings look in the manual

I compressed it, but I have to share my internet connection with my brother and upload is like hell Sad The -m switch didn´t helped as I tested it with fasmw!

The problem is caused by this line in your task_t structure:
Code:
        .name                   rb (256 - .name)    

which, when the current offset is above 256, tries to reserve the negative amount of bytes. That was also indeed a flaw in fasm, since it was signaling the wrong error message - I've updated the 1.62 with the fix. Thanks for the report.

OK, but what have I to write that I get the value "256 - offset of .name in the structure"?

In general, the offset of .name is the address of .name minus the address of the structure. You can use some additional label:
Code:
struc foo
 {
   .start:
   .name  rb 256 - (.name-.start)
 }    


But since you define also "task_t task_t" at address 0 to get the structure offset, the simplest should be just:
Code:
.name                   rb (256 - task_t.name)

to the first one
Code:
struc foo{
local ..start
..start:
.name rb 256 - ..start
}    

just like first privalov's, but this way you won't get defined additional label task_t.start and won't change namespace for some very special causes.

Even better:
Code:
struc foo
 {
   .:
   .name  rb 256 - (.name-.)
 }    

this one doesn't use any additional label at all.
