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"><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" target="_blank">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>
