<div dir="ltr"><div><div><div><div><div>All,<br><br></div>I have reported this problem before, but I am reporting it again because it seems as if it has not been fixed. I continually get crashes when I run the Mac OS-X versions of the precompiled IPOPT mex files. I do not know why the crash occurs, but it happens frequently and it seems as if it is specific to the Mac. An example of the crash is shown the following crash dump file.<br><br></div>To be honest, I have no idea why such a problem exists on a Mac (which is UNIX, so I would expect better reliability). This problem does not seem to occur on a Windows machine (makes me want to switch to Windows, perish the thought!). Anyway, any help is greatly appreciated. <br><br></div>On a separate note, are there IPOPT mex files (or equivalent) for languages such as Python, R, or Julia? If so, has anyone uploaded precompiled versions of such executables for these other languages? Finally, would any such mex files have MA57 capability, or would they be limited to just being able to use Mumps? <br><br></div>Thanks in advance for any help anyone can provide.<br><br></div>Anil Rao<br><br><div><div><div><div><div><br><br><br><br>------------------------------------------------------------------------<br> abort() detected at Mon Mar 9 19:45:44 2015<br>------------------------------------------------------------------------<br><br>Configuration:<br> Crash Decoding : Disabled<br> Crash Mode : continue (default)<br> Current Graphics Driver: Unknown hardware <br> Current Visual : Quartz<br> Default Encoding : ISO-8859-1<br> Host Name : Anils-MacBook-Pro.local<br> MATLAB Architecture : maci64<br> MATLAB Root : /Applications/MATLAB_R2015a.app<br> MATLAB Version : 8.5.0.197613 (R2015a)<br> OpenGL : hardware<br> Operating System : Darwin 14.1.0 Darwin Kernel Version 14.1.0: Mon Dec 22 23:10:38 PST 2014; root:xnu-2782.10.72~2/RELEASE_X86_64 x86_64<br> Processor ID : x86 Family 6 Model 58 Stepping 9, GenuineIntel<br> Virtual Machine : Java 1.7.0_60-b19 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode<br> Window System : Quartz<br><br>Fault Count: 1<br><br><br>Abnormal termination:<br>abort()<br><br>Register State (from fault):<br> RAX = 000000011c373af8 RBX = 0000000000000000<br> RCX = 0000000000000003 RDX = 000000011c37209c<br> RSP = 0000000000000016 RBP = 00007fff8d7f09a7<br> RSI = 000000011c372080 RDI = 000000011c380000<br><br> R8 = 0000000000000006 R9 = 00000001513467a5<br> R10 = 000000011c372660 R11 = 000000011c380000<br> R12 = 00007f9497aa2600 R13 = 000000011c3720b0<br> R14 = 00007fff8d7f142f R15 = 0000000000000000<br><br> RIP = 00004d031c3720d0 RFL = 000000011c3720d0<br><br> CS = 000000011c3722b0 FS = 000000011c3720e0 GS = 00007fff9c0c4b53<br><br>Stack Trace (from fault):<br>[ 0] 0x000000011044e964 /Applications/MATLAB_R2015a.app/bin/maci64/libmwfl.dylib+00031076 _ZN2fl4diag15stacktrace_base7captureERKNS0_14thread_contextEm+00000052<br>[ 1] 0x000000011045202b /Applications/MATLAB_R2015a.app/bin/maci64/libmwfl.dylib+00045099 _ZN2fl4test17terminate_handledEv+00000763<br>[ 2] 0x0000000110451ac7 /Applications/MATLAB_R2015a.app/bin/maci64/libmwfl.dylib+00043719 _ZN2fl4diag13terminate_logEPKcPK17__darwin_ucontext+00000119<br>[ 3] 0x000000010ff74f9b /Applications/MATLAB_R2015a.app/bin/maci64/libmwmcr.dylib+00380827 _Z32mnRunPathDependentInitializationv+00002875<br>[ 4] 0x000000010ff75217 /Applications/MATLAB_R2015a.app/bin/maci64/libmwmcr.dylib+00381463 _Z32mnRunPathDependentInitializationv+00003511<br>[ 5] 0x000000010ff74908 /Applications/MATLAB_R2015a.app/bin/maci64/libmwmcr.dylib+00379144 _Z32mnRunPathDependentInitializationv+00001192<br>[ 6] 0x000000010ff742cc /Applications/MATLAB_R2015a.app/bin/maci64/libmwmcr.dylib+00377548 _Z22mnInstallCrashHandlersv+00000236<br>[ 7] 0x00007fff9385ef1a /usr/lib/system/libsystem_platform.dylib+00020250 _sigtramp+00000026<br>[ 8] 0x0000000000000000 <unknown-module>+00000000<br>[ 9] 0x00007fff9c0c4b53 /usr/lib/system/libsystem_c.dylib+00383827 abort+00000129<br>[ 10] 0x0000000151397fb6 /Users/anilvrao/Documents/MATLAB/GPOPS-II/R2-May-2014/nlp/ipopt/ipopt.mexmaci64+03760054 uw_init_context_1+00000134<br><br><br>This error was detected while a MEX-file was running.
