The linker bug was meanwhile fixed. Unfortunately I didn't save any of the broken executables - the referenced bug says libstdc++ tests were broken, but as far as I remember every executable compiled with -g -flto -Wl,--gc-sections was broken due to stripped relocations. It might be possible to dig out an old BFD ld and create an affected executable that way (plus old gdb to check if the segfault was reproducible). Not sure if worth - feel free to close the bug instead. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 2+ messages in thread
