For me, it's the following:
- Arch Linux (everything up to date, as always)
- gc=7.4.2
- guile=2.0.11

Works fine even a thousand times with guile disabled, yes.

> Still, does gdb hang *before* the program is run?

Just tried this with a trivial, single-threaded Hello World program, a few runs
*did* actually lock up before the program was run. Interestingly, ^C works in
that case and gives me a gdb prompt.

Multi-threaded programs will almost always hang on thread creation, which
indeed happens far more often.

Again, this only goes for the guile-enabled version. Without guile, I cannot
reproduce any lockup.
