Well, now we are into your territory, I hope you can figure it out. What I can tell you is binutils-2.35.2 and earlier have been working solid reliable for a long time, years. I noticed you are using the -T flag. The FPC specifically doesn't use that, something to do with the builtin system script that they override with their own, or the other way round. For a possible clue, here is what the FPC devs had a guess it relates to, copied from the FPC bug report I put at https://gitlab.com/freepascal.org/fpc/source/-/issues/39324 https://wiki.freepascal.org/User_Changes_3.2.0#GNU_Binutils_2.19.1_or_later_are_required_by_default GNU Binutils 2.19.1 or later are required by default Old behaviour: The compiler invocation of the linker always resulted in a warning stating "did you forget -T?" New behaviour: The compiler now uses a different way to invoke the linker, which prevents this warning, but this requires functionality that is only available in GNU Binutils 2.19 and later. Reason: Get rid of the linker warning, which was caused by the fact that we used the linker in an unsupported way (and which hence occasionally caused issues). Remedy: If you have a system with an older version of GNU Binutils, you can use the new -X9 command line parameter to make the compiler revert to the old behaviour. You will not be able to (easily) bootstrap the new version of FPC on such a system though, so use another system with a more up-to-date version of GNU Binutils for that. --- https://gitlab.com/freepascal.org/fpc/source/-/commit/4564bffb85e5947cf7bdfa3e2c67bc032775d0c5 * use binutils 2.19+ linker script "augmentation" functionality to specify how the fpc sections have to be linked *on Linux*. This prevents the "did you forget -T" warnings from ld, and in general is more correct than our previous approach of specifying a complete linker script without -T and hoping that there won't be any unexpected interactions with ld's built-in linker script (fixed version of r31664, thanks to Alan Modra) o use the new -X9 command line option to generate linker scripts that are compatible with binutils older than 2.19 (reverts to the old behaviour) Note it is *not* confirmed that this is the actual issue here. This prior issue relates to something in binutils 2.19, whereas I have fully confirmed this current issue is between binutils-2.35 and 2.36. Maybe it's the same problem, or not. -- You are receiving this mail because: You are on the CC list for the bug.
