DWARF Information not Used with Wildcards

Hi,

I’ve a problem with commit 5ef0c24456e3279cda2f444e9db0a3292388cdd7.

When the commit is applied, the output of running the command (simplified)
stap -L 'process("/lib64/libcarplay-plugin-core.so").function("*").call' | grep RTPJitterBufferRead
yields
process("/lib64/libcarplay-plugin-core.so").function("RTPJitterBufferRead").call

Seemingly, the DWARF information is ignored.

When I revert the commit and run the same command, I get the following output
process("/lib64/libcarplay-plugin-core.so").function("RTPJitterBufferRead@Sources/AirPlayUtils.c:1261").call $ctx:RTPJitterBufferContext* $inBuffer:void* $inLen:size_t

What’s strange is that 
stap -L 'process("/lib64/libcarplay-plugin-core.so").function("RTPJitterBufferRead").call‘
shows the correct output in both cases.

Kind Regards,
Torsten
