egcs gives internal compiler error

[Erik Rissanen <mirty at bahnhof dot se>]

Hi, and thanks for your work on egcs/gcc.

Here is a bug report. It's an internal compiler error.

I don't know enough of C++ to know if the code that triggers the bug is 
correct or not. The code is from the mnemonic web browser.

My machine is a Pentium Pro 180 overclocked to 200, with 96 megabytes of main 
memory. I am quite certain that the problem is not hardware related, since the 
processor has ran overclocked and reliable for three years, and I can 
reproduce the problem with different versions of egcs.

I use Linux 2.2.10, glibc 2.1.1 and binutils 2.9.1.0.25.

The version of egcs is what I got when I today (July 26 1999) checked out the 
gcc 2.95 branch from CVS. I compiled and installed it as follows:

../egcs/configure --prefix=/usr/local/egcs-cvs-990726 --enable-threads
--enable-version-specific-runtime-libs
make -j 3 bootstrap
make install

(All in a separate build directory running as root.)

Here is the full command line with -v --save-temps added and the output. Also 
included as an attachment to this mail is the thread.ii file.

The installation instructions for mnemonic told me to set LD_LIBRARY_PATH 
to "/home/erikr/mnemonic-install:/home/erikr/mnemonic-install/msg".
(Though I cannot imagine that it would matter anything in this case.)

I hope this report will be useful to you.
