Floating point exception before main () function

[delt]

Hello everyone, new user here from Montréal, Canada.

I'm getting a weird FPE crash in what looks like a string-conversion function in wxWidgets, whenever i link my executable with wxSVG - this crash is probably caused by some global object's constructor because it happens before the start of my main function is even reached.

Here's a backtrace from gdb:

Program received signal SIGFPE, Arithmetic exception.

As you can see, this gets called directly from the linker as soon as anything using anything from wxSVG is in my code.... any ideas? Thanks in advance for any insight/assistance.

Oops sorry my bad, the issue was caused by mixing static and dynamic libraries, and/or position-idependant with non-PIC.
