The following script runs successfully on ppc64 when compiled with
elfutils-0.135 but fails on ppc64 with elfutils-0.137
probe kernel.function("__vm_enough_memory")
{
printf("sysctl_overcommit_ratio = %d\n", $sysctl_overcommit_ratio)
}
The stack backtrace for the failure :

-------------------------------------------------------------------------
Looks like an issue with dwfl_addrmodule.c
( I'm labelling this as a translator bug since I couldnt find a separate section
for elfutils-bugs )
