C++ source code
I just tried to compile the package efte-1.1-6
on gcc-4.9 trunk dated 20130508 on an AMD x86_64 box.
The compiler said
/home/dcb/rpmbuild/BUILD/efte-1.1/src/h_c.cpp:32:5: internal compiler error:
Aborted

glibc said
*** glibc detected ***
/home/dcb/gcc/results/libexec/gcc/x86_64-unknown-linux-gnu/4.9.0/cc1plus:
free(): invalid next size (fast): 0x000000000346d8d0 ***
It looks to me like some memory allocation goes wrong because
glibc complains.
Preprocessed source code attached. Flag -O2 required.
