--- Comment #18 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:047c0fae82ca1458339e7e9724d125d30b685898 commit r11-10776-g047c0fae82ca1458339e7e9724d125d30b685898 Author: Jonathan Wakely <jwak...@redhat.com> Date: Tue Nov 22 09:53:36 2022 +0000 libstdc++: Fix pool resource build errors for H8 [PR107801] The array of pool sizes was previously adjusted to work for msp430-elf which has 16-bit int and either 16-bit size_t or 20-bit size_t. The largest pool sizes were disabled unless size_t has more than 20 bits. The H8 family has 16-bit int but 32-bit size_t, which means that the largest sizes are enabled, but 1<<15 produces a negative number that then cannot be narrowed to size_t. Replace the test for 32-bit size_t with a test for 32-bit int, which means we won't use the 4kiB to 4MiB pools for targets with 16-bit int even if they have a wider size_t. libstdc++-v3/ChangeLog: PR libstdc++/107801 * src/c++17/memory_resource.cc (pool_sizes): Disable large pools for targets with 16-bit int. (cherry picked from commit 0f9659e770304d3c44cfa0e793833a461bc487aa)
