This patch fixes a "set but not used" warning from dlfcn/failtestmod.c. A variable is used only to store the return value from dlsym. As I understand this test, the point is simply to do a sequence of load / unload operations in a loop, and all that matters here is that dlsym gets called and returns without crashing, not what its return value is. So this patch removes the assignment to a variable. Tested for x86_64. * dlfcn/failtestmod.c (constr): Do not store result of dlsym in a variable.
