--- Comment #4 from seurer at gcc dot gnu.org --- So, adding in a -g3 I see: Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this error: #0 0x3fffb7f80477 in ??? #1 0x10000878 in MAIN__ at /home/seurer/gcc/gcc-test2/gcc/testsuite/gfortran.dg/proc_ptr_51.f90:35 #2 0x10000878 in main at /home/seurer/gcc/gcc-test2/gcc/testsuite/gfortran.dg/proc_ptr_51.f90:32 Segmentation fault line 35 of the test case is: res => c_() which looks like some kind of call via a function pointer maybe? Is there some specific trace or dump that would help you that I could generate? Be specific about options if so please. Assembler listing maybe?
