You can start with trying if -O2 -fno-inline -fno-inline-small-functions is
still miscompiled and if -O0 works, then you can add
__attribute__((__optimized__([02]))) to suspected functions.

You need to make sure to include the pch only from the toplevel source.
Otherwise
interesting things may happen. A convenient way to do so is to include the
pch via the -include command-line option.

"sqrtf" but not with -m64 with "logf". (Compile with "-fsignaling-nans" and

Hmm... I have ensured that the #include chain in every source file results in

include utils.h, which includes system.hh. And so, it works with 4.2

On this computer, the main disk is labeled H:\, and GCC won't so much as print
its version. It repeatedly causes crss to throw a No Disk error, which doesn't
accept cancel as an answer. Can't really isolate problem; don't have access to
any other computers without C:\ as main drive, and since it wo

functions. Here is an example:
