Created attachment 46971 [details] repro.c gziped (3Mb uncompressed) libgccjit get ice in subsequent compilations. the attached reproducer compiles code A then B and then recompiling A crash. I struggle to create a minimal artificial reproducer so I attach the auto-generated one that is rather big. I'm quite sure this is related to static structures we store into gcc/ipa-prop.c and I'm currently looking into it. $ gcc repro.c -O0 -g3 -o repro -lgccjit $ ./repro compiling A compiling B compiling A during IPA pass: cp libgccjit.so: error: in operator[], at vec.h:859 0x7f54abfc412f vec<tree_node*, va_heap, vl_embed>::operator[](unsigned int) ../../gcc/vec.h:859 0x7f54abfc412f vec<tree_node*, va_heap, vl_ptr>::operator[](unsigned int) ../../gcc/vec.h:1425 0x7f54abfc412f ipcp_update_bits ../../gcc/ipa-prop.c:5026 0x7f54abfc412f ipcp_transform_function(cgraph_node*) ../../gcc/ipa-prop.c:5202 0x7f54ac6888e4 execute_one_ipa_transform_pass ../../gcc/passes.c:2231 0x7f54ac688a59 execute_all_ipa_transforms(bool) ../../gcc/passes.c:2270 0x7f54ac107000 cgraph_node::expand() ../../gcc/cgraphunit.c:2187 0x7f54ac1076d4 expand_all_functions ../../gcc/cgraphunit.c:2332 0x7f54ac1083dc symbol_table::compile() ../../gcc/cgraphunit.c:2688 0x7f54ac10887d symbol_table::finalize_compilation_unit() ../../gcc/cgraphunit.c:2868 Please submit a full bug report, with preprocessed source if appropriate. Please include the complete backtrace with any bug report. See <https://gcc.gnu.org/bugs/> for instructions. This reproducer output was run on the current trunk (gcc 10 37584e9) but I see it affect at least also the gcc-9-branch.
