Hi,

After recent upgrade, FreeSWITCH was unable to start.
During startup, it generates SIGSEGV, and terminated.

I investigated, what happening, and found - problem was in the obsolete
mod_file_string (see debug log below).
I disabled load this module, and FS works OK.

I think, need remove this module from the repository, or make another
steps, for preserve this crash.

Thanks,

Oleg
