Block nesting error

[mineiro]

I'm receiving Block nesting error if I try to use invoke inside (.init) segment.
I'm missing something? Linux x86-64.

I've not tried using anything but the simplified directives with linux, I will have to investigate this.

[johnsa]

have you tried setting up the segment without the alias? and possibly try adding some other directives like use64 etc.

[mineiro]

Thanks for answering sir johnsa.
Yes, I tried that but no luck.

The segment name should start with a dot.
If I use code below, program works, but when I try to use invoke in that segment so the message of Block nesting error appear.

option dotname
.fini segment
.fini ends

I tried the assume directive to set the segment registers, without success. I tried to set the use of segments before their use, but without success.
I tried to not use CStr, and invoke works fine.
So, sounds that it's CStr my problem. It's just for convenience, no need to worry.
