Lets try
/kodi> ( setenv LD_AUDIT ./auditmod.so ; ./foo )
version: 2
memset: dst=0x404060, src=0x3, len=33
pltenter: memset: dst=0x404060, src=3, len=33
yep
/kodi> ( setenv LD_AUDIT ./auditmod.so ; setenv LD_PRELOAD
/lib64/libmemusage.so ; setenv MEMUSAGE_OUTPUT /dev/null ; setenv
MEMUSAGE_TRACE_MMAP yes ; /usr/lib64/kodi/kodi.bin )
version: 2
Segmentation fault (core dumped)
libmemusage does not allow ... then without
/kodi> ( setenv LD_AUDIT ./auditmod.so ; /usr/lib64/kodi/kodi.bin ) | & tee
audit.log
... that is a longer list, see attachment
