problem with gawk CONVFMT

[Alain NOULLEZ]

Hello,

I have got a strange bug (crash) when converting a variable inside a loop
modifying at the same time CONVFMT.
The strange thing is that it seems converting a real variable to a string can
cause a modification of the variable itself, against all expectations.
The minimal program causing the crash is included.  As such, it crashes
with the message "fatal error: internal error" (or segfaults on some
machines).
If the line s = x "" is commented, and the line containing the gensub is
uncommented, the program goes into an infinite loop.  Also, if the
initialization
of CONVFMT is uncommented, the program crashes in some cases, but not
always ?!?.
For information, gawk's version is 3.1.8
and my system 'uname -a' is
Linux ### 2.6.34.7-66.fc13.i686.PAE #1 SMP Wed Dec 15 07:21:49 UTC
2010 i686 i686 i386 GNU/Linux

Thanks a lot in any case for gawk, and I hope you can understand and solve
that problem.
Best regards,
A. Noullez.
