<div dir="ltr">Hi Hava,<div><br></div><div>That'd be very difficult to determine with that traceback! I'd recommend compiling FLASH in debug mode as a start to have a traceback to work with and then you can work with (parallel) debugging tools too. Or if the error is late in the evolution (or disappears during debug mode) add print statements to understand the order of execution and where the segfault occurs. Often my segfaults are related to indexing out of bounds - but other causes are possible too.</div><div><br></div><div>Best,<br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr">--------<div>Ryan</div></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jun 22, 2022 at 9:43 PM Hava Turkakin <<a href="mailto:turkakin@ualberta.ca">turkakin@ualberta.ca</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi everyone</div><div>I would appreciate it if anyone could tell me what might be the reason for the following run time error! <br></div><div>forrtl: severe (174): SIGSEGV, segmentation fault occurred<br>Image              PC                Routine            Line        Source<br>flash4             00000000006DC36A  for__signal_handl     Unknown  Unknown<br>libpthread-2.30.s  00002B147B3DB0F0  Unknown               Unknown  Unknown<br>libiomp5.so        00002B147BAEE465  Unknown               Unknown  Unknown<br>libiomp5.so        00002B147BAEF537  Unknown               Unknown  Unknown<br>flash4             000000000070B7B0  for_alloc_allocat     Unknown  Unknown<br>flash4             00000000004B43AF  Unknown               Unknown  Unknown<br>flash4             000000000045FBE1  Unknown               Unknown  Unknown<br>flash4             0000000000437A36  Unknown               Unknown  Unknown<br>flash4             0000000000414CA9  Unknown               Unknown  Unknown<br>flash4             000000000041B4DE  Unknown               Unknown  Unknown<br>flash4             000000000040CE52  Unknown               Unknown  Unknown<br><a href="http://libc-2.30.so" target="_blank">libc-2.30.so</a>       00002B147B40BE1B  __libc_start_main     Unknown  Unknown<br>flash4             000000000040CD6A  Unknown               Unknown  Unknown<br></div><div>Thank you </div><br clear="all"><br>-- <br><div dir="ltr">PhD<br>University of Alberta<br>Department of Physics</div></div>
