--- Comment #7 from Sam James <sjames at gcc dot gnu.org> --- Created attachment 62135 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=62135&action=edit pr121572-elfutils.tar.xz At r16-3190-g5cf1b9a03ec5b6, I noticed some bugginess with consumers of elfutils/libelf (libdwfl) error handling. With your patch (the one posted last night), I get an ICE with elfutils at a different place to Sergei's above testcase. I didn't clean it up, cvise only now finished. I'll try the new patch. But for now: ``` + gcc -O3 -flto=auto -fPIC -o libdw.so -shared -o libdw.so -Wl,--version-script=libdw.map -Wl,--whole-archive dwarf_error.os dwfl_begin.os dwfl_error.os argp-std.os -Wl,--no-whole-archive + cat x.txt argp-std.i:13:6: warning: type of ‘dwfl_begin’ does not match original declaration [-Wlto-type-mismatch] 13 | int *dwfl_begin(Dwfl_Callbacks *); | ^ dwfl_begin.i:9:6: note: type mismatch in parameter 1 9 | int *dwfl_begin() { __libdwfl_seterrno(DWFL_E_LIBELF); } | ^ dwfl_begin.i:9:6: note: ‘dwfl_begin’ was previously declared here during RTL pass: x86_cse argp-std.i: In function ‘parse_opt’: argp-std.i:29:1: internal compiler error: in ix86_place_single_tls_call, at config/i386/i386-features.cc:3873 29 | } | ^` ```
