[Rust] BNUpdateAnalysisAndWait hangs after BNLoadFilename(_, updateAnalysisAndWait=false, _)

[jrozner]

Version and Platform (required):

• Binary Ninja Version: dev
• Edition: Ultimate
• OS: linux
• OS Version: 24.04
• CPU Architecture: x64

Bug Description:
The two-step "load without analyzing, then analyze separately" pattern hangs forever on at least some ELFs. BNLoadFilename(path, updateAnalysisAndWait=false, …) returns successfully, but a subsequent call to BNUpdateAnalysisAndWait never returns, and BNGetAnalysisProgress reports Initial indefinitely. The single-call form BNLoadFilename(path, updateAnalysisAndWait=true, …) analyzes the same file to completion in seconds.

Steps To Reproduce:

fn main() {
  let session = binaryninja::headless::Session::new().unwrap();

  // Single-call form: completes in seconds, BV ends up fully analyzed.
  let bv = session
      .load_with_options("/path/to/bin", true, Some("{}"))
      .expect("load failed");
  // bv.analysis_progress() == Idle here.

  // Two-step form: hangs indefinitely on the same file, never leaves Initial.
  let bv = session
      .load_with_options("/path/to/ioncube_loader_lin_8.3.so", false, Some("{}"))
      .expect("load failed");
  assert!(matches!(
      bv.analysis_progress(),
      binaryninja::binary_view::AnalysisProgress::Initial
  ));
  bv.update_analysis_and_wait(); // never returns
}

*Expected Behavior:
bv.update_analysis_and_wait should finish
