Managed to trig it with 7.7:
| > strlen(Image.JPEG.encode(Image.JPEG.decode(Stdio.read_bytes("DSC00354.JPG"))->scale(0.1))); | *** glibc detected *** pike-7.7: munmap_chunk(): invalid pointer: 0x0000000000b27ea0 *** | ======= Backtrace: ========= | /lib/libc.so.6(cfree+0x1b6)[0x2acff84d3d46] | /usr/lib/libjpeg.so.62[0x2acff9a24ffa] | /usr/lib/libjpeg.so.62[0x2acff9a250fb] | ...
(Just had to switch from Image.load to the above construct.)
Image exists as http://www.mirar.org/DSC00354.JPG if anyone wants to try it. I'll see if I can get valgrind running tomorrow (remind me if I forget).
