In my system, running Vivid, the SegvAnalysis shows the source as
"0x18(%rax)", but the address is 0x00000018 (which it also says it's not
located in a known VMA). The StacktraceTop shows pa_hashmap_new_full
instead of pa_hashmap_new. Apart from that, the details are basically
identical to those of this bug report.
