--- Comment #11 from Andrew Teylu <andrew.teylu at vector dot com> --- Ah, no, I think Eric is correct in that it doesn't work at all (even if gcc doesn't fail). I used https://github.com/Microsoft/microsoft-pdb/blob/master/cvdump/cvdump.exe to look at the pdb file generated when compiling/linking my example, and the `*** LINES` section looked like this: ``` ** Module: "D:/DEV/msys64/home/ateylu/alire/tom_121157/v3/b~main.o" Mod::GetEnumLines failed ** Module: "D:/DEV/msys64/home/ateylu/alire/tom_121157/v3/main.o" ** Module: "D:/DEV/msys64/home/ateylu/alire/tom_121157/v3/local_io.o" ``` Notice: for the two files we compile with `-gcodeview` they _do not_ have `Mod::GetEnumLines failed` (which, I think, means there is PDB info for those objects, but it is empty). I then wrote a matching C version (including a binder main that I did not compile with `-gcodeview` to match what I did for Ada), and the `*** LINES` section looked like this: ``` ** Module: "D:/DEV/msys64/home/ateylu/alire/tom_121157/v3/c/b_main.o" Mod::GetEnumLines failed ** Module: "D:/DEV/msys64/home/ateylu/alire/tom_121157/v3/c/main.o" D:/DEV/msys64/home/ateylu/alire/tom_121157/v3/c/main.c (MD5: 7935177CE228764361F5487B3BDA29AC), 0001:000005E0-000005F7, line/addr pairs = 3 4 000005E0 5 000005E8 6 000005F0 ** Module: "D:/DEV/msys64/home/ateylu/alire/tom_121157/v3/c/local_io.o" D:/DEV/msys64/home/ateylu/alire/tom_121157/v3/c/local_io.c (MD5: 5997CD3181362A6DA3EF9CCAA4E0B36D), 0001:00000600-0000060B, line/addr pairs = 3 4 00000600 5 00000604 6 00000609 ``` That is, there is the debug information for the object files (and, as we'd like, not for the binder main).
