No UDT's as macro parameters allowed
« on: December 14, 2018, 06:25:32 PM »
 This has been giving me trouble. apparently Oxygen hates when UDT variables are passed as macro parameters and commits suicide.

Code: [Select]
   SOMEUDT u1

   A_MACRO(u1, b, c, d)

 It consistently crashes. even worse when its an array of UDT's.
Please give it a check when you can? If not too difficult?

 I am trying to implement TYPE SET.

Example:

Code: [Select]
'Generated with PluriBASIC 6.0.74371.0

$ filename "MACROUDTS.exe"

uses rtl64

TYPE UDT1
    CHAR x[12]
END TYPE

MACRO SOMEMACRO(a)

END MACRO

UDT1 u1

somemacro(u1)
 
FUNCTION PBMAIN() AS INT
   INT _FUNCTION = 0
END FUNCTION

PBMAIN() ' invoke entry point

Oddly, in some of my bigger examples, using UDTs in macros are completely fine, so, something else must be fixing the issue.

Wow. Actually this is also crashing:

Code: [Select]
$ filename "MACROUDTS.exe"

uses rtl64

macro somemacro(u1)
end macro

long a

somemacro(a)

Maybe empty macros are killing it... this fixes the crash for normal variables:

Code: [Select]
macro somemacro(u1)
    u1 = 1
end macro

Hi Brian,

There was a substitution problem with empty macros.

Now Fixed:
