GDB Incorrectly Reads & Resolves Shared Library Symbols [MinGW-w64]

[William Adair]

Hannes,

Unfortunately, I do not. It appears I'm left with little choice but to
debug GDB itself while it's debugging the executable that loads the shared
library. I'll add that I am using a custom linker command file and that may
be ruining some predefined expectation from GDB on what data should be in
certain sections, but I haven't dug far enough into GDB source to figure
out how it loads symbols from the binary image, yet.
