gcc48: f951: internal compiler error: Illegal instruction

[nicolaiheitz@…]

Configuring and compiling of standard libraries like scalapack and hdf5 fails due to an internal compiler error. A minimal error example is attached as well as the output it produces:

Please run the compiler back-end in lldb:

lldb -- /opt/local/libexec/gcc/x86_64-apple-darwin11/4.8.2/f951 mini.f -ffixed-form -fPIC -quiet -dumpbase mini.f -mmacosx-version-min=10.7.4 -mtune=core2 -auxbase mini -version -fintrinsic-modules-path /opt/local/lib/gcc48/gcc/x86_64-apple-darwin11/4.8.2/finclude -o /var/folders/9y/l6x_lpzn68lfv0667l0gmcfw0000gn/T//ccwFY8D6.s

as in #41555, and post the results.

Try reinstalling gmp from source (with "-s"):

port -f uninstall gmp
port -s install gmp

Does this fix your problem?

[nicolaiheitz@…]

It does fix my problem.

Thank you so much for your support!

[kurtjaeke@…]

So, can this issue be closed, then?
