The hypothesis is...actually, no, i have no idea. I mean, it's obvious that= gdb expects to find that section in a separate debug file for some reason. Prob= ably because separate debug files are just PE binaries, and the code that reads = them is heavily re-used. Or maybe gdb supports recursive debuglinks? Either way, the workaround, as you've already surmised, is to placate gdb by adding a .gnu_debuglink section to the separate debug file. The trick is to ensure that it passes the CRC32 check.
