pcb-printf in gerber.c corrupt gerber outputs

The gerber output of this file has drill holes clustered around the origin and silkscreen artefacts at y=720" when viewed in gerbv.

I am also running F14 x64 and cannot reproduce this bug.

Can you post your ~/.pcb/preferences file?

Can you reproduce this with the latest git HEAD? We have recently fixed a gerber output bug that (maybe) is the same as this one.

Just tried to reproduce with current git head and the preferences above.
→ no holes at the origin, no obvious silk glitches in the gerbers

Does not seem to reproduce with current versions of pcb
