Description

Dear Singular devs,

I've met a segfault using blowUp from resolve.lib. Here is the output :

blowUp(IA,JA);

Singular : signal 11 (v: 3110/2010030316): current line:>> ideal W=preimage(T,phi,W);<< Segment fault/Bus error occurred at c01e3e because of 3f7ffebc (r:1273053658) please inform the authors trying to restart... Auf Wiedersehen.

================================================

Here is the output :

Center(J);

_[1]=t _[2]=z _[3]=y _[4]=x

resolve(J,31);

? not implemented

Singular : signal 11 (v: 3110/2010030316): current line:>> pr = facstd(i);<< Segment fault/Bus error occurred at 81b0888 because of c (r:1273055397) please inform the authors trying to restart...

? error occurred in or before primdec.lib::radical line 5747: pr = facstd(i); ? leaving primdec.lib::radical

Auf Wiedersehen.

Replying to broustet@…: Dear Amael,

thank you for reporting the problem. To diagnose the reasons for this error we would need to know the input which led to it. Please make sure that you also include information on the used version of Singular, the operating system and possibly other information which might be relevant for recreating the circumstances of your problem on our machines.

Best regards, Anne
