And I think it will still fail a --disable-shared build without having a libgc.la. The alternative would be to run the to-be-generated LIBTOOL_COMPILE and LIBTOOL_LINK in the configure file.

We're just in a transition state this release as we flatten to reconstruct a more sensible modular layout. this is for 4.10, but what to do about 4.9? Maybe have gimple-plugin.h and tree-plugin.h headers, which won't go away for 4.10 and then would just include gimple.h and tree.h? I would appreciate if you could name all the toplevel headers.

Cause: The function pari_init_parser() in the file src/language/parsec.h is miscompiled. (This file is included by src/language/parse.y). If you replace the line 43: s_node.n=OPnboperator; by parsestate_reset(); (which does the same thing), then all test pass. It seems that the issue is that the function stack_alloc() is not inlined correctly, which cause pari_tree to be NULL (or maybe the call to pari_inline inside stack_alloc() is not inlined correctly. The command line used is gcc-4.6 -c -O3 -Wall -fno-strict-aliasing -fomit-frame-pointer-I. -I../src/headers -fPIC -o parse.o ../src/language/parse.c It also happens with -O2, but not with -O3 -fno-inline.

seen with current 4.5 and 4.5 branches, and trunk
g++-4.4 miscompiles complex division:

#include complex
#include iostream
void f(std::complexdouble x)
{
std::cout x std::endl;
x = 1.0 / x;
std::cout x std::endl;
}
int main()

f(2.0);
}
