Reading a std::array<Long64_t, 1> from a TFile created on linux does not work on macOS #9001
Closed as duplicate
Description
To reproduce, download http://ccdb-test.cern.ch:8080/download/d64bd450-1619-11ec-a9d5-200114580202 and open it in TBrowser. Works on ubuntu, but on mac I get:
root [2] Error in <TBufferFile::ReadVersion>: Could not find the StreamerInfo with a checksum of 0xdc6299b4 for the class "array<Long64_t,1>" in /Users/ktf/Downloads/array<Long64_t,1>_1631706076679.root.
Error in <TBufferFile::CheckByteCount>: object of class array<Long64_t,1> read too few bytes: 6 instead of 14
when clicking on ccdb_object;1.
Both ROOT 6.24.02 and 6.24.06 seem to be affected.

Notice that using a
std::vectorin place of astd::arrayworks as expected.pcanal commentedon Sep 16, 2021
Does the reading work properly on the same platform (both no warning and the correct value)? What is the array value for the example provided?
ktf commentedon Sep 16, 2021
yes. Reading it back on linux works just fine.

The actual value should be some timestamp around 1630659771715.

:) ok. That's what I get, that looked like a random stream :) .. well not quite the same but similar (
1631706076551146), I assume it is a different filektf commentedon Sep 16, 2021
yeah, I cannot check the actual value right now, but it looks correct.
