[asan] Fix a thinko leading to a crash
It appeared that in my previous patch, a stupid thinko can lead to a
crash when instrumenting some builtin functionsK. Fixed thus.
Bootstrapped and tested against trunk on x86_64-unknown-linux-gnu.
gcc/
* asan.c (instrument_builtin_call): Really put the length of the
second source argument into src1_len.
gcc/testsuite/
* c-c++-common/asan/memcmp-2.c: New test.
