Hi there,
Today I downloaded the [mpich-announce] MPICH 5.0.0 released
on a x86_64-pc-linux-gnu Linux machine with Fedora 43.
Although the building is fine, the following warning appears during
compilation:
../src/mpid/ch4/src/ch4_proc.c: In function ‘MPIDIU_upidhash_add’:
../src/mpid/ch4/src/ch4_proc.c:336:5: warning: ‘memcpy’ specified
bound between 18446744071562067968 and 18446744073709551615 exceeds
maximum object size 9223372036854775807 [-Wstringop-overflow=]
336 | memcpy(t->upid, upid, upid_len);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I'd like to know if it can be ignored, or if it would be better to fix it (and
how to do so). Thanks,
Regards.
Jorge D'Elia.
