>Description:
I get a testsuite error in g++.dg/ext/instantiate2.C as seen here:  http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg00233.html

This appears to be a (long standing) regression from gcc-3.2.x since the same testcase appears there and does not fail.


The logfile says:
FAIL: g++.dg/ext/instantiate2.C scan-assembler
_?_ZN1AIiE1tE(:|
|       )

>How-To-Repeat:
Target mips-sgi-irix6.5 and compile instantiate2.ii with:

cc1plus -fpreprocessed instantiate2.ii -quiet -dumpbase instantiate2.C -auxbase-strip instantiate2.s -version -fmessage-length=0 -fno-implicit-templates -o instantiate2.s

and note that the scan-assembler pattern doesn't appear in the .s file.

    The problem seems to have disappeared sometime around Feb 26.  Wish we knew why, I feel uncomfortable closing this without confirmation that the bug is fixed rather than hidden...
