Comment after macro with arguments breaking next line parsing

[FlyGoat]

Hi all,

I found a very wired behaviour in preprocessor:

case1.sv

`define FOO(n)   n // comment
`define BAR     10'h03E

module top();
  wire  [9:0] a;
  assign a = `BAR;
endmodule

With surelog surelog -nobuiltin -nocache -writeppfile /dev/stdout case1.sv:

[INF:CM0023] Creating log file "/***/slpp_all/surelog.log".
[ERR:PP0102] /***/case1.sv:8:14: Unknown macro "BAR".






module top();
  wire  [9:0] a;
  assign a = SURELOG_MACRO_NOT_DEFINED:BAR!!! ;
endmodule


[  FATAL] : 0
[ SYNTAX] : 0
[  ERROR] : 1
[WARNING] : 0
[   NOTE] : 0

Verilator verilator -E ./case1.sv :

`line 1 "case1.sv" 1
 
 

`line 4 "case1.sv" 0
module top();
  wire  [9:0] a;
  assign a = 10'h03E;
endmodule


`line 10 "case1.sv" 0

For context:

surelog --version
VERSION: 1.84
BUILT  : Dec  8 2024

Any idea what's going on here?

Thanks!
