Siddhesh Poyarekar <siddhesh at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |siddhesh at redhat dot com --- Comment #2 from Siddhesh Poyarekar <siddhesh at redhat dot com> --- It's because libpthread dynamically loads libgcc_s.so.1. As a result there are two copies of dwarf_reg_size_table, where one (the dynamic one) is initialized and the other (the static one) is used, resulting in this crash.
