Test case (205 bytes, text/plain)

Description Ed Schouten 2007-08-28 18:10:38 UTC 
Please describe the problem:
The vala compiler bails out when the following piece of code is compiled:

class A : B {
}
class B {
}

with the following error messages:

test.c:19: error: field 'parent' has incomplete type
test.c:23: error: field 'parent' has incomplete type
error: cc exited with status 256
Compilation failed: 1 error(s), 0 warning(s)

This is because the B and BClass structs are already used before they are declared. This is because C uses a single pass compiler.

Steps to reproduce:


Actual results:


Expected results:


Does this happen every time?

Comment 1 Ed Schouten 2007-08-28 18:20:15 UTC 
Strange thing is: it only happens with Vala from SVN; not 0.1.2.
Comment 2 Jürg Billeter 2007-08-28 18:31:32 UTC 
Confirming, happens with trunk and 0.1.2 here.

Appears to be fixed in SVN rev 600

Jürg,

I'm still running vala with the patch I've attached in  Bug 530063. Otherwise my code does not compile. I'm surprised to see that this bug has severity minor and priority low.
