https://community.hpe.com/t5/operating-system-hp-ux/mlib-8-3-core-dump/m-p/2775563#M722374 I don't know about the mlib thing, but as this happened just after an upgrade I would suggest findout out what patch matrix is required for *that version* of mlib, and checking you have the latest patches. I've tripped over that problem in java often enough ;-)<BR /><BR />Cheers!<BR />James Tue, 30 Jul 2002 12:43:47 GMT James Beamish-White 2002-07-30T12:43:47Z https://community.hpe.com/t5/operating-system-hp-ux/mlib-8-3-core-dump/m-p/2775562#M722373 I have a program which uses the sparse matrix solver in mlib. It works fine with mlib version 8.1. However, after I updated the mlib to version 8.3, I got a core dump when "dslevm()" is called for the symmetric matrix. The error message "SIGSEGV, Segmentation fault" was from "cxd_dinpnv()" which was called by "dslevm()".<BR /><BR />Any help is appreciated.<BR /><BR />Dong Zheng Tue, 30 Jul 2002 12:40:37 GMT https://community.hpe.com/t5/operating-system-hp-ux/mlib-8-3-core-dump/m-p/2775562#M722373 Dong Zheng 2002-07-30T12:40:37Z https://community.hpe.com/t5/operating-system-hp-ux/mlib-8-3-core-dump/m-p/2775563#M722374 I don't know about the mlib thing, but as this happened just after an upgrade I would suggest findout out what patch matrix is required for *that version* of mlib, and checking you have the latest patches.
