Dear all, I am on debian jessy 64bit and after installing sage 7.3 I keep getting segfault for the same worksheets that run smoothly in sage 6.8. I have now managed to isolate a small example, which I uploaded to cloud.sagemath, where it does not give a segfault message, but just runs forever. To use locally, download this file:
https://cloud.sagemath.com/projects/34b4b62a-2621-47c8-9bda-cde3a855f995/files/leaf_chamber_eqs_PM.sobj then run the following code in a sagenb notebook: vdict = cdict.copy() vdict[a_s] = 1 vdict[L_l] = 0.07 vdict[P_a] = 101325 vdict[P_wa] = 20/1000*101325 vdict[R_s] = 400 vdict[Re_c] = 3000 vdict[T_a] = 273+30 vdict[T_w] = vdict[T_a] vdict[g_sw] = 0.15/40 vdict[v_w] = 1. vdict[nu_a] = eq_nua.rhs().subs(vdict) print eq_Re.subs(vdict) Here are the error messages I get in the terminal: 2016-09-08T15:04:22+0200 [stdout#info] raise NoFunctionNameInFrameError() 2016-09-08T15:04:22+0200 [stdout#info] NoFunctionNameInFrameError: C function name could not be determined in the current C stack frame 2016-09-08T15:04:22+0200 [stdout#info] close failed in file object destructor: 2016-09-08T15:04:22+0200 [stdout#info] IOError: [Errno 9] Bad file descriptor 2016-09-08T15:04:22+0200 [stdout#info] 2016-09-08T15:04:22+0200 [stdout#info] Saved trace to .../.sage/crash_logs/crash_XdQCv0.log 2016-09-08T15:04:22+0200 [stdout#info] ------------------------------------------------------------------------ 2016-09-08T15:04:22+0200 [stdout#info] Unhandled SIGABRT: An abort() occurred. 2016-09-08T15:04:22+0200 [stdout#info] This probably occurred because a *compiled* module has a bug 2016-09-08T15:04:22+0200 [stdout#info] in it and is not properly wrapped with sig_on(), sig_off(). 2016-09-08T15:04:22+0200 [stdout#info] Python will now terminate. 2016-09-08T15:04:22+0200 [stdout#info] ------------------------------------------------------------------------ I'm sure the example could be simplified much more, but I hope this helps to track down the problem. The worksheet can also be found on cloud.sagemath: https://cloud.sagemath.com/projects/34b4b62a-2621-47c8-9bda-cde3a855f995/files/sigsegv_7.3.sagews -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
