some application hang on FreeBSD

[Riccardo Mottola]

Hi,

on FreeBSD 7.2, running on x86, some application hang for me at startup. 
Many work. The same apps


for example, FTP (Available from GAP) hangs at startup. No menu, no user 
interface element becomes visible. If I break into the app, I get this 
stacktrace:

I have another app, sourcecode not yet pulished, which appears to hang 
the same way:

Could these hangs be due to the recent pthread changes by David?
