I guess it would help quite a bit if a simpler repro was made available. I don't think what is provided in the bugzilla entry is quite suitable for anyone not familiar with MingW.

But maybe one, who is familiar with the internals of binutils, can guess what is wrong, being provided with the file names and lines: binutils-gdb/bfd/cofflink.c:2279 binutils-gdb/bfd/coff-x86_64.c:696 https://sourceware.org/bugzilla/show_bug.cgi?id=29389 Thank you!

I'm sorry, the reality is that trying to debug remotely is extremely time consuming and frustrating for everyone involved. > > But maybe one, who is familiar with the internals of binutils, can > > guess what is wrong, being provided with the file names and lines: > > > > binutils-gdb/bfd/cofflink.c:2279 > > binutils-gdb/bfd/coff-x86_64.c:696 All that says to me is "something went wrong", likely long before the assertions triggered. If you expect someone to look at your bug, you need to package up a set of object files so that someone can reproduce the problem by running the linker on an entirely different machine. Note that the inputs to the linker are needed, not source files. We don't want to and can't debug your compiler for you.. That means *all* the inputs to ld, so system libraries too. Please do test that what you package up is a complete testcase, by running a cross-linker on a non-windows machine. -- Alan Modra Australia Development Lab, IBM ^ permalink raw reply [flat|nested] 6+ messages in thread

Luca has provided some important information on this issue: https://sourceware.org/bugzilla/show_bug.cgi?id=29389#c2 1. Do you still need some more input on this? 2. Is there a chance that the fix for this will enter the version 2.39? Thank you!
