Thread: pgsql: Fix pointer cast for seed calculation on 32-bit systems
Fix pointer cast for seed calculation on 32-bit systems The fallback seed for when pg_strong_random cannot generate a high quality seed mixes in the address of the conn object, but the cast failed to take the word size into consideration. Fix by casting to a uintptr_t instead. The seed calculation was added in 7f5b19817e. The code as it stood generated the following warning on mamba and lapwing in the buildfarm: fe-connect.c: In function 'libpq_prng_init': fe-connect.c:1048:11: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 1048 | rseed = ((uint64) conn) ^ | ^ Author: Hayato Kuroda <kuroda.hayato@fujitsu.com> Discussion: https://postgr.es/m/TYAPR01MB58665250EDCD551CCA9AD117F58E9@TYAPR01MB5866.jpnprd01.prod.outlook.com Branch ------ master Details ------- https://git.postgresql.org/pg/commitdiff/2fe7a6df94e69a20c57f71a0592133684cf612da Modified Files -------------- src/interfaces/libpq/fe-connect.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
