Dear Andrey,

I do think so! How else would I have these cyg*.dll.dbg?

-rwx---r-x 1 hans hans 594632 Mar  3 10:07 
/lib/debug//usr/bin/cygquadmath-0.dll.dbg
-rwx---r-x 1 hans hans 3526482 Mar  3 10:07 
/lib/debug//usr/bin/cyggfortran-3.dll.dbg

-rwx---r-x 1 hans hans 497181 Feb 23 17:07 /usr/bin/cygquadmath-0.dll
-rwx---r-x 1 hans hans 1023517 Feb 23 17:06 /usr/bin/cyggfortran-3.dll

Anyhow, looking more closely, I noticed the different file dates. 
Manually removing the above and re-installing all gcc + gcc debuginfo 
packages solved the issue. The sigfe.s problem has gone as well as the 
CRC mismatches.

thx. for making me look more closely!

H.
