Hi Honza, It looks like cgraph_fnver_htab defined in cgraph.c is not added to gc root in gt-cgraph.h. This patch fixes it.
* cgraph.c (cgraph_fnver_htab): Move GTY((...)) to be before htab_t. Change param_is to use the struct and not the pointer to the struct. Index: gcc/cgraph.c =================================================================== --- gcc/cgraph.c (revision 204022) +++ gcc/cgraph.c (working copy) @@ -138,7 +138,7 @@ bool cpp_implicit_aliases_done; The cgraph_function_version_info has a THIS_NODE field that is the corresponding cgraph_node.. */ -static htab_t GTY((param_is (struct cgraph_function_version_info *))) +static GTY((param_is (struct cgraph_function_version_info))) htab_t cgraph_fnver_htab = NULL; /* Hash function for cgraph_fnver_htab. */ Ok to submit? Thanks Sri
