Summary
When multiple Charm gems (bubblezone, lipgloss, bubbletea, etc.) are loaded together in the same Ruby process, calling Go-backed functions causes a segfault due to Go runtime symbol clashes. Each gem embeds a full Go runtime via
c-archive, and the duplicate symbols collide when both runtimes are active.This is especially problematic with cross-compiled gems (via rake-compiler-dock), where Ruby's rbconfig adds
-Wl,-flat_namespace- putting all symbols into a single global pool.Fix
-load_hiddento link the Go static archive with all symbols hidden, and-exported_symbolto export only_Init_bubblezone.--exclude-libs,ALLto hide all symbols from the Go static archive.Same fix as marcoroth/lipgloss-ruby#5 and marcoroth/bubbletea-ruby#4.
