[lttng-dev] Problem using pthread and libc wrapper

Hi Martin, 

Can you reproduce with the latest stable branch (2.7.x) or with master 
of lttng-ust and lttng-tools ? 

New in lttng 2.7 is the renaming of some providers to add proper name spacing: 

ust_pthread -> lttng_ust_pthread 
ust_libc -> lttng_ust_libc 

Thanks, 

Mathieu
