--- Comment #1 from Maarten Lankhorst bugs@mblankhorst.nl --- Affects ubuntu too, adding -fno-optimize-sibling-calls to CXXFLAGS and CFLAGS for armhf can work around it.
This appears to be a toolchain bug, probably caused by the following code in radeon_drm_bo.c:
void *radeon_bo_do_map(struct radeon_bo *bo) { ... }
static void *radeon_bo_map(struct radeon_winsys_cs_handle *buf, struct radeon_winsys_cs *rcs, enum pipe_transfer_usage usage) { ... return radeon_bo_do_map(bo); }
