19336d2 effectively removed AsciiDoc support by deleting the reference to the lexer module:
The upshot is that sci_set_lexer() now gets a null pointer from LexerNameFromID() when catalogueLexilla.Find() fails to map SCLEX_ASCIIDOC to a module, and CreateLexer() ends up calling strcmp(NULL, ...). The faulting instruction is deep inside the standard C library; you need an IDE with a disassembly viewer to see it precisely, e.g.
// __strcmp_sse42 (@__strcmp_sse42:12)
// . . .
7FFFF799021A: F3 0F 6F 16 movdqu (%rsi), %xmm2 // RSI: 0x0000000000000000
// . . .Or just take a backtrace with GDB. Simply try to open any AsciiDoc file, et volià!

Rebuilding Geany after patching the module reference back in will fix it. I would open a PR but I'm not sure if Lexilla changes are supposed to be recorded in scintilla_changes.patch or not. The patch is pretty out of date already, so I don't mind leaving this for someone else 😉.
