Well, working with mono-1.2.5.1 on my FreeBSD 7.1-PRERELEASE box is
okay. Since I can't have mono >=1.2.6 on FreeBSD I am still using it.  I
I can't however be sure that nothing has been changed in FreeBSD since
Mono 1.2.6 was released that could affect mono.

Just tried it. Instead of hanging-on, mono aborts. The backtrace in gdb
is almost the same, plus ~10 frames that look consistent and are related
to signal handling:

Previous frame inner to this frame (corrupt stack?)
(gdb) 

The line « warning: Source file is more recent than executable. » makes
me feel uncomfortable however.
