Matthias Klose <doko at ubuntu dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |doko at ubuntu dot com --- Comment #2 from Matthias Klose <doko at ubuntu dot com> 2011-05-02 17:05:14 UTC --- have a similiar build failure, but seen with both 4.6 and 4.7, so this seems to be a 4.6 regression too. works with -O2 and below. fails with 4.6 20110428 and trunk 20110419. $ gcc -g -O3 -c psf.i psf.c: In function 'psf_fit': psf.c:300:6: internal compiler error: Segmentation fault Please submit a full bug report, Program received signal SIGSEGV, Segmentation fault. 0x000000000083e71a in build2_stat () (gdb) bt #0 0x000000000083e71a in build2_stat () #1 0x00000000005490ee in gimple_assign_rhs_to_tree () #2 0x000000000080114e in insert_debug_temp_for_var_def () #3 0x0000000000801538 in insert_debug_temps_for_defs () #4 0x000000000062553a in gsi_remove () #5 0x0000000000763862 in ??
