Subject: configure: Fix type of argument to backtrace_symbols
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=61a1d95c6f9de3973dd1e6da4f151de856e00e86;p=thirdparty%2Ffreeradius-server.git

configure: Fix type of argument to backtrace_symbols

The backtrace_symbols function expects a pointer to an array of
void * values, not a pointer to an array of a single element.
Removing the address operator ensures that the right type is used.

This avoids an unconditional failure of this probe with compilers
that treat incompatible pointer types as a compilation error.
