Thanks Thomas, Philippe and I were aware of it. Buried in the messages between us I had made the comment below to him. References to AC_PROG_CC_STDC are part of using -std=c99 as part of the compiler options and what optimization level you use also factors in. No optimizations seems to work. -------------------- I rebuilt it from tagged 1.05 sources in CVS and the problem didn't occur. I then built it from HEAD and it worked. I sent you an email that seems to suggest the issue is with Optimizations (-O0 seems to work) / compiling with --std=c99 / and some issue with the C Runtime (And it could be related to something in our code that makes this appear. If it is a bug it is something that seems to affect the runtime code prior to main() being called. The error you see under Ubuntu 15.04 is actually the same thing I see on 14.04 depending on the optimization level I use. If I remove all the std=c99 stuff from configure.ac that has been added then it seems to work fine no matter the optimization level. -- Michael Petch CApp::Sysware Consulting Ltd.
