What is the expected output? What do you see instead?

Error during compile:

error: invalid conversion from ‘void (*)(int, siginfo_t*, void*)’ to ‘void (*)(int,
int*, void*)’

What version of the product are you using? On what operating system?

Using gperftools 2.0 on Ubuntu 14.04 (error occurs on Ubuntu 14.04, also using Ubuntu
10.04 & 12.04, Debian 6 & 7, RHEL 5 & 6, and SLES 11).

Please provide any additional information below.

This is very similar to issue # 444. That problem was solved with s/siginfo_t/siginfo/,
but this appears to be solved with s/siginfo_t/int/. Making that change appears to
compile correctly on all the operating systems mentioned above.
