[Valgrind-users] helgrind segfaulting

[Yasushi S. <ys...@hp...>]

Here's a really simple program:

#include <netdb.h>
int main()
{
    gethostbyname("www.yahoo.com");
}

When I compile this program on Redhat 8 (glibc-2.2.93-5, gcc-3.2-7) and run it under helgrind (1.9.6), it dumps core.


% cc -pthread foo.c
% valgrind --skin=helgrind a.out

By the way, this problem doesn't happen with valgrind 1.9.3, but it does with 1.9.5. Any help is appreciated..

thanks,
