--- Comment #17 from Richard Biener <rguenth at gcc dot gnu.org> --- Does it still happen (branch/trunk?)? Sorry if I have not been of help :/ The original error is from torture-init in torture-options.exp. torture-init is called explicitely from gcc.dg/torture/tls/tls.exp and from gcc-dg.exp in the gcc-dg-runtest procedure but only conditional on # Some callers set torture options themselves; don't override those. set existing_torture_options [torture-options-exist] if { $existing_torture_options == 0 } { global DG_TORTURE_OPTIONS LTO_TORTURE_OPTIONS torture-init that said, somehow one needs to trace the TCL code on how we arrive with torture options set. Do you maybe have some local board file setting torture_without_loops?
