Please look at the asm dump (add -S to compile flags) for following lines:
.globl iint
.bss
.align 4
.type iint, @object
.size iint, 4
iint:
.zero 4
.comm iarr,256,32 <<<< this one
alternatively, you can use -fno-common:
.globl iarr
.align 32 <<<< alignment
.type iarr, @object
.size iarr, 256
iarr:
.zero 256
In above dump (linux target) iarr is aligned to 32bytes. Does cygwin aligns
.comm variables to multiplies of 16 bytes?
