SIGSEGVs with g++3.2

[Richard Guenther <rguenth at tat dot physik dot uni-tuebingen dot de>]

Hi!

I just tried todays gcc 3.2 branch and encountered SIGSEGVs in many
programs which look like

(gdb) run
Starting program: /net/bellatrix/home/rguenth/src/pooma-work/rhalk/Shock1d

Program received signal SIGSEGV, Segmentation fault.

(gdb)

Does this look familiar to anybody?

bellatrix:~/src/pooma-work/rhalk$ ldd ./Shock1d
        libhdf5.so.0 => /home/rguenth/ix86/lib/libhdf5.so.0 (0x40017000)
        libm.so.6 => /lib/libm.so.6 (0x40119000)
        libc.so.6 => /lib/libc.so.6 (0x40138000)
        libz.so.1 => /lib/libz.so.1 (0x40254000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

btw - this is on a SuSE 7.2 system. Oh - gcc 3.0.4 works without a
problem.
