strstr() on CentOS 5.10 may be too old.
Yes it is. But 'configure' is supposed to detect this. config.log should say something like this:
configure:26283: checking whether strstr works in linear time configure:26357: gcc -std=gnu99 -o conftest -g -O2 conftest.c >&5 configure:26357: $? = 0 configure:26357: ./conftest configure:26357: $? = 142 configure: program exited with status 142This is how it behaves for me, on RHEL 6.5 and on Solaris 11.1. Could you please investigate why it is not occurring on CentOS 5.10? For example, why does the attached program work? It should fail.
strstr-test.c
