Hi Orion:Thanks for your report.

Therefore, I assume you meant camlidl rather than ocaml above.
Indeed, sorry for the confusion.

But my OCaml (and camlidl) knowledge is pretty limited as well soI don't understand (at all) how that simple result is implemented with the macros #define QUOTEME(x) #x #define RAW_ML(x) quote(mlmli, QUOTEME(x)); So I also hope you can get help from Richard on how this result is generated, but since the result is so simple, my best guess is this issue is due to a bug in the particular pre-release 1.0.8 version that Fedora has decided to package. I am tied up with a large number of different projects for the next month or so. But when I get a free moment (and if this Fedora issue has not been resolved by then), I will attempt to obtain the latest camlidl from <https://github.com/xavierleroy/camlidl> to see if I can replicate the issue you have found. N.B. from the latest commit message there, 1.0.8 hasn't actually been released yet. Therefore, if the issue is because of a bug in the particular pre-release version of camlidl that Fedora has packaged, then it is alway possible that Xavier Leroy has already fixed this bug in a later pre-release version. But if changing the Fedora package to the latest pre-release version does not fix the current issue, then I would recommend you contact Xavier Leroy about this issue to see if he can fix it before he releases 1.0.8. Good luck, and let me know how it goes. Alan
I've filed this with camlidl: https://github.com/xavierleroy/camlidl/issues/18 hopefully they can help. -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane or...@nwra.com Boulder, CO 80301 https://www.nwra.com/
