It would seem that GCC 4.5.1 is still generating a call to func(), at -Os.
Considering the following reduced test-case:

extern int outcnt;
void test ()
{
 outcnt = 0;
 if (outcnt == 1) func ();
 if (outcnt == 1) func ();
 if (outcnt == 1) func ();
 if (outcnt == 1) func ();
 if (outcnt == 1) func ();
 if (outcnt == 1) func ();
 if (outcnt == 1) func ();
 if (outcnt == 1) func ();
}

At -O2:

/usr/libexec/gcc/x86_64-redhat-linux/4.5.1/cc1 -O2 -o - test.c
.file   "test.c"
 test

Some random config of the linux kernel, as of 2.6.36-rc3 results on the
following

In case that help, this compiler was build with the latest GMP/MPC/MPFR.

Compilers from the same code tree, but built for PowerPC or Sparc target, run
fine.

[Bug bootstrap/41818] Error building cross compiler caused by changing LD_LIBRARY_PATH environment variable in Makefile

ok, 3.4.5, same target is bad too:

./mips-unknown-linux-uclibc/libstdc++-v3/config.log:
error while loading shared libraries:
/targets/mips-unknown-linux-uclibc/build/build-cc/./gcc/libgcc_s.so.1: ELF file

I encountered that issue with gcc 4.3.4 on the following target:
mips-unknown-linux-uclibc. I'm currently confirming with gcc 4.3.5. If it still
happen, would it be worth pulling to the 4.3 branch ?

--- Comment #2 from lacombar at gmail dot com  2010-04-23 22:15 ---
can you provide a backtrace of this crash ? What is the version of the system
compiler used for that build ?

Thanks.

[Bug target/43873] Bootstrap compiler segfault while configuring libgcc

--- Comment #1 from lacombar at gmail dot com  2010-04-23 22:02 ---
building for `i486-pc-elf' and `arm-unknown-eabi' using the same system
toolchain works fine. I'll try to build for more target over the week-end to
confirm if it's a blackfin-only issue or not.
