Hello,

according to the trace, the crash trace is:

#0  0x00007f544c119801 in _IO_default_xsputn_internal () from
/lib64/libc.so.6
No symbol table info available.
#1  0x00007f544c0e93a9 in vfprintf () from /lib64/libc.so.6
No symbol table info available.
#2  0x00007f544c0f4368 in fprintf () from /lib64/libc.so.6
No symbol table info available.
#3  0x00007f544c189bc8 in __vsyslog_chk () from /lib64/libc.so.6
No symbol table info available.
#4  0x00007f544c18a210 in syslog () from /lib64/libc.so.6
No symbol table info available.
#5  0x00007f54479f2341 in pv_get_ruri_attr (msg=0x7f544bed9c30,
param=0x7f544beb2a50, res=0x7fffe1341e88) at pv_core.c:304
        __FUNCTION__ = "pv_get_ruri_attr"

Line 304 in pv_core is:
        LM_ERR("failed to parse the R-URI\n");

Which is a bit strange as a point of crash. I will try to see if I can
spot something else...

I noticed that you seem to have somehow kind of infinite loop with
calling route blocks - like calling route B from A and route A from B...

Cheers,
Daniel
