RDM Linux - Crash during clipboard operation

Hello,

This post is a follow-up to a crash reported separately from the sleep/resume issue in the original thread. The crash described here was observed while actively using an RDP connection, with no obvious trigger at the time, though clipboard activity had been occurring.

Symptom:
RDM aborts during or shortly after a clipboard set operation while an RDP session is active.

What the core dump shows:
The crash is a Signal 6 (ABRT), not a segfault. The crashing thread was executing RDM's clipboard code via the .NET runtime (libcoreclr.so), calling into gtk_clipboard_set_with_data through GTK/GDK/libX11/libxcb. At that point, glibc's memory allocator detected a corrupted heap chunk (tcache_get_n -> malloc_printerr -> abort).

This is a distinct crash from the sleep/resume one and is being tracked separately by the same user.
