Breakpoint 4, __interception::InterceptFunction (name=0x3fffd61e8f2 "regexec",
ver=0x3fffd61eb7e "GLIBC_2.3.4", ptr_to_real=0x3fffd677d08
<__interception::real_regexec>, func=16779728,
wrapper=4398001883504) at
/devel/gcc-4/src/libsanitizer/interception/interception_linux.cpp:74
74 void *addr = GetFuncAddr(name, ver);
At the end of InterceptFunction we have:
(gdb) print addr
$1 = (void *) 0x3fffd2e9110 <__GI___regexec>
The address itself also LGTM, i.e., `readelf -s /lib64/libc.so.6 | grep
regexec` results in:
279: 00000000000e9110 344 FUNC GLOBAL DEFAULT 13 regexec@@GLIBC_2.3.4
...
25156: 00000000000e9110 344 FUNC LOCAL DEFAULT 13 __GI___regexec
However, variables func and wrapper differ
(gdb) print func
$2 = 16779728
(gdb) print wrapper
$3 = 4398001883504
so we return false.
