When compiling ChucK, g++ complains that the function sprintf is undeclared in util_string.cpp. Sure enough, stdio.h is not included in util_string.h (or in chuck_def.h). After adding the following line to either util_string.h or chuck_def.h, ChucK compiles successfully - but I then get seg faults when running simple example code (e.g., examples/moe.ck). Any ideas? Verbose output from ChucK leading up to the seg fault is below.
