I’ve compiled asterisk 184.108.40.206 on Debian testing (partly out-of-date), according to the freepbx docs, and it gives the preceding error (when combined with gdb). It gives it even if no configuration files are present, and asterisk-addons has not yet been installed. The last system call was munmap.
linux 220.127.116.11 (stock)
gcc 4.0.3 and later 3.3
The CPU is a VIA Samuel 2, according to /proc/cpuinfo. I have no special hardware installed; I doubt sound even works.
I’m happy to supply more info, try tweaking things, etc.
Many thanks for any advice,
