--- Comment #10 from Christophe Lyon <clyon at gcc dot gnu.org> --- I checked the stack settings on the ARMv7 and ARMv8 machines: ARMv7: beced000-bed0e000 rw-p 00000000 00:00 0 [stack] ARMv8: fff12000-fff33000 rw-p 00000000 00:00 0 [stack] In both cases ulimit -a says: stack size (kbytes, -s) 8192 I recompiled with "-Os -flto -g -mthumb" (ie. I added -g) and execution sometimes reaches iteration 2, sometimes not. Using gdb I got a bit more info: Program received signal SIGSEGV, Segmentation fault. _int_free (av=0xc59a20, p=<optimized out>, have_lock=12975032) at malloc.c:4088 4088 malloc.c: No such file or directory. But this is random too, another run gave: Program received signal SIGSEGV, Segmentation fault. __brk (addr=0x1) at ../sysdeps/unix/sysv/linux/arm/brk.c:31 31 ../sysdeps/unix/sysv/linux/arm/brk.c: No such file or directory. Other runs from the same gdb gave no backtrace at all, and at least one of them reached iteration 4.
