This series contain fixes for winedump for debug information: - it fixes a bunch of incorrect information dumping, - it fixes a case of crash for .DBG files, - it allows dumping very large PDB files (>4G)
Note: for the later item, current tools' read_file() doesn't work with such large files. Instead of fixing read_file(), I opted for letting a dumper for a given file format to only use a fd to the target file, instead of forcing all dumpers to work from a full in-memory image of the target file. This is useful for PDB files, as their underlying storage requires to reassemble non-contiguous blocks, so this saves memory (the in-memory image of the target file) and one copy of the whole file. This means that all functions to guess the file format now uses a fd instead of the full image.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=151092
Your paranoid android.
