In some code reading

void* (*gcl_gmp_allocfun)(size_t) = alloc_relblock;

void *
alloc_relblock(size_t n) {



when compiled linked and the run under gdb, broken at main:

(gdb) p *gcl_gmp_allocfun == alloc_relblock
$1 = 0
(gdb) p gcl_gmp_allocfun == alloc_relblock
$2 = 0
(gdb) p gcl_gmp_allocfun
$3 = (void *(*)(size_t)) @0x746caa: 0x74760c
(gdb) p alloc_relblock
$4 = {void *(size_t)} 0xd538c <alloc_relblock>

Why is the static initialization failing?

Take care,
