1.4.22 crashing on Solaris in ast_dynamic_str_thread_build_va
Hello,
Asterisk 1.4.22 keeps crashing on Solaris 5.10 i386.
ast_dynamic_str_thread_build_va() seems to be passed some kind of
garbage (see attached dbx output) which ultimately brings down the
whole process. As a workaround, I've set the debug level to 0 for now.
Should I submit this as a bug?
Thanks for any help. Best,
Peter
