And worse, the problem goes away when building without optimization.
There might be another GCC bug lurking in the background...


Probably there is more than one.
I hit a gcc-4.8 optimization bug testing slang, the workaround
was to build the 64 bit package without any optimization.


slang is written in c++?


in C


And you built it with the default -mcmodel=medium, I assume.  Well,
it's not that gcc would be entirely bug free and 4.8.1 is lurking
around the corner already.  Any chance to create a simple testcase?


default -mcmodel=medium

Slang is a small library and the failure is
during "make check" when UTF8 is not used

about the test, I need to look, but I will wait after 4.8.1
