@barracuda156 Thanks for reporting this bug. I was aware of this bug. However, because it belongs to an older version (1) of the library, we have not (been able to) introduce a patch for it. The new experimental release of the library resolves this bug completely (which is not unique to PowerPC/macOS). The issue is that the first argument of writeDecoratedList is declared as allocatable with intent(in), which the older compilers did not catch as a bug and hence remained hidden. Is there any reason to use this older version of the library instead of the experimental release (which will soon be the stable release)?

[barracuda156]

@shahmoradi Nothing in particular, I just saw that 1.5.2 was still considered a stable release, and it was building earlier (perhaps with gcc 13 if not 12).
I can try building from the master.

@shahmoradi I tried building 2024.04.29, it fails to link for me: #51
