Description (last modified by ryandesign (Ryan Carsten Schmidt))

When compiling a certain file, gcc-11 produces:

../../../libssSPM/libssSPM/include/ssSPM/salford/safe_exports.h:450:1: internal compiler error: Illegal instruction: 4
  450 | static const double Percentile[N_PERCENTILE_STATS]               = {      0.01,         0.02,         0.025,        0.03,          0.04,         0.05,         0.10,         0.20,         0.25,            0.30,         0.40,         0.50,                0.60,         0.70,         0.75,            0.80,         0.90,         0.95,         0.96,         0.97,          0.975,         0.98,         0.99    };

N_PERCENTILE_STATS is a macro defined as 23

Changing the location or formatting of the statement fails to eliminate the internal error. Commenting out the above data structure does cause the error to go away, though, of course, the source file fails to compile due to its absence.

The following compile-time flags are specified:

-O -m64 -fopenmp -Wcomment -Wformat -Wuninitialized -Warray-bounds -Wno-deprecated-declarations -Wno-write-strings -Wno-sizeof-array-argument -fopenmp -std=gnu++14

The OS version is 15.6.0

Sounds like something you should report to the developers of gcc. You may want to first check whether it has already been fixed in the latest version of gcc (available in the gcc-devel port).

Development version does the same thing. So does gcc5. I think I'll try 4.9.

comment:4 Changed 3 years ago by jlries61 (John L. Ries)

4.9 does the same, even though no version of gcc did this the last time I tried to build this software under OSX three years ago. Some additional printout:

../../../libssSPM/libssSPM/include/ssSPM/salford/safe_exports.h:450:1: internal compiler error: Abort trap: 6 g++: internal compiler error: Abort trap: 6 (program cc1plus) make: * [mainc.o] Abort trap: 6

Is this still an issue with the latest gcc11 ?

We'll find out now that GCC 11 is built on the offending machine.
