Not on my system, BTW: $ ldd /usr/bin/gawk linux-vdso.so.1 => (0x00007fffe5b54000) libdl.so.2 => /lib64/libdl.so.2 (0x0000003291400000) libm.so.6 => /lib64/libm.so.6 (0x0000003291000000) libc.so.6 => /lib64/libc.so.6 (0x0000003290c00000) /lib64/ld-linux-x86-64.so.2 (0x0000003290800000) AFAICS Fedora guys uses --with-libsigsegv-prefix=no for gawk since 2009.
