our fellas ran into this issue, which boiled down to finding [
sourceware.org] and reading man 3 printf (search for NOTES and/or undefined). Page [
web.mit.edu] even includes grep on afni for points to fix... meanwhile here is the result of such undefined behavior unfortunately with our NeuroDebian build where we use
-D_FORTIFY_SOURCE=2
since few months back (I really need to cook up more tests ;) )
$> /usr/lib/afni/bin/ccalc -eval 1000 \* 10
10.000000
$> /usr/lib/afni/bin/ccalc -eval '1000 * 10'
10000.000000
As a workaround I will disable fortification for now in our build.
