Bug 198528 (PR32177) – [4.2/ICE] gcc-4.2.2 with -fopenmp generates internal compiler error

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Bryan Green 2007-11-09 03:39:21 UTC]

Compiling an openmp C++ program with gcc-4.2.2 caused an internal compiler error.
This is the message printed:
g++ -c -O3 -fopenmp -o genfield.o genfield.cxx
genfield.cxx: In function 'int main(int, char**)':
genfield.cxx:0: internal compiler error: in lower_stmt, at gimple-low.c:282

I'm attaching the preprocessed source.


Reproducible: Always

Steps to Reproduce:
1.g++-4.2.2 -fopenmp -c genfield.preproced.cxx

Actual Results:  
genfield.cxx: In function 'int main(int, char**)':
genfield.cxx:0: internal compiler error: in lower_stmt, at gimple-low.c:282
Please submit a full bug report,
with preprocessed source if appropriate.

always post files as attachments, do not post links to files

if the file is too big, compress it

genfield-reduced.ii

ugly reduced test case ... i'm not a C++ pro, so someone else might be able to whittle it down further

[Comment 5 SpanKY 2008-02-17 08:19:02 UTC]

looks like PR32177 ... i'll test the patch there
