pin-linux does not intercept strlen #54

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
This is caused by the lack of support of IFUNC symbols in PIN. 
See http://tech.groups.yahoo.com/group/pinheads/message/5599

You can see it e.g. like this: 
 ./tsan_pin_debug.sh  ../unittest/bin/racecheck_unittest-linux-amd64-O0 --gtest_filter=NegativeTests.StrlenAndFriends
