+qemu-system-arm segfaults while servicing SYS_HEAPINFO
+
+I compiled QEMU version 5.2.0 from source on Ubuntu 18.04, and tried to use it to run the attached bare-metal Arm hello-world image, using the command line
+
+qemu-system-arm -M microbit -semihosting -nographic -device loader,file=hello.hex
+
+The result was that qemu-system-arm itself died of a segfault. Compiling it for debugging, the location of the segfault was in target/arm/arm-semi.c, in the case handler for the semihosting call TARGET_SYS_HEAPINFO, on line 1020 which assigns to 'rambase':
+
+            const struct arm_boot_info *info = env->boot_info;
+            target_ulong rambase = info->loader_start;
+
+and the problem seems to be that 'info', aka env->boot_info, is NULL in this context.
