I was showing my son how to use PSPP to analyze some survey data and I crashed PSPP. I'm using GNU pspp 1.2.0-g0fb4db on Windows 7 (yeah, I know). This happens reliably for me. A mingw window pops up saying an assertion failed:
The text reads: Assertion failed! Program: C:\Program Files\PSPP\bin\PSPPIRE.exe File: src/data/case.c, Line 476 Expression: caseproto_get_width(c->proto, case_idx) == var_get_width(v) Steps to replicate: *Step 1.* Download this SPSS system file of survey data: https://faunalytics.org/wp-content/uploads/2017/04/Faunalytics-Current-Former-Veg-Study-Dataset-All-Respondents-Original-Variables.sav (Described on this page: https://faunalytics.org/dataset-study-of-current-and-former-vegetarians-and-vegans/) *Step 2: *Find VEG_RECIDIVISTS_1_SQ001 in the data editor variable view (row 66) and change the Type to numeric (leave the default %2.0f) *Step 3:* Open a new syntax file (File > New > Syntax) and paste these two FREQ routines FREQUENCIES /VARIABLES= VEG_RECIDIVISTS_1_SQ001 to VEG_RECIDIVISTS_1_SQ010 /FORMAT=AVALUE TABLE. FREQUENCIES /VARIABLES= VEGAN_RECIDIVISTS_1_SQ001 to VEGAN_RECIDIVISTS_1_SQ010 /FORMAT=AVALUE TABLE. *Step 4:* Run this syntax twice (Run > all, then Run > all again). The assertion pops and PSPPIRE closes when you select Abort. If you omit Step 2, it doesn't seem to occur, so I guess there's some issue changing the type. (I know, BTW, that changing the type is a bad idea because it forces all the data in that variable to be missing.) -Alan -- Alan D.
