Thank you very much, Alan and Nick!
Is it safe to backport this patch to the 2_39 branch? Let me know, otherwise we
can simply add a downstream patch in MSYS2.
Cheers,

On MSYS2, bfd/cache.c:bfd_cache_max_open() returns 10, while on Linux it
returns 128 (because HAVE_GETRLIMIT is defined)
If I force the cache size on MSYS2 to a higher value, e.g. 500, then the issue
goes

Uh...how strange!
One of the very first things that _bfd_coff_link_input_bfd() does is call
obj_coff_external_syms() which seeks into the lib file and reads the external
symbols table.

The code that repeatedly calls _bfd_coff_link_input_bfd() is in

I have now more insights into what's going on...
The issue stems from passing repeated import libs to the linker:
ld.bfd -o out ... subprojects/glib/gobject/libgobject-2.0.dll.a ...

Right now I have just tried debugging this issue in GDB a bit. What I could

Scratch the above comment, as the steps are not useful at all. This can be
reproduced on MSYS2 as reported on the GitHub issue.
