Dear GCC folks,
may I humbly put in a word for my dear bug 29609,
which is very close to my heart?
I write most of my C code in the style
if (!do_something(...))
goto failure_handler;
and letting the debugger stop at the 'goto' line is
quite important to finding bugs quickly.

Hi,
I'm following a strange bug in MySQL Debian package for ARM plateforms:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=411427
It seems that compiling the exact same code without optimization option
make it works.
Could somebody take a quick look at the thread (link given before) and
tell m

Probably/maybe/possibly. It also could be the case that MySQL is doing

In what sense is it a builtin if it requires a library to be installed and
emits a call to a library function ??? I may not have understood what you're
trying to do here, but how would it b

Thank to both of you (Andrew and Jack), I'll dig this deeper anyway.

A question for the C++ maintainers considering the lvalue-ness of
NON_DEPENDENT_EXPR expressions...
As part of tightening up our checking of non-dependent expressions
within templates (and necessary step for C++0x, and a good idea in
C++98 anyway), I bumped into this bit of code in lvalue_p_1:
We would like to announce the availability of the "Intel IEEE 754r
Decimal Floating-Point BID Library" (beta version), at
http://www3.intel.com/cd/software/products/asmo-na/eng/219861.htm under
'Decimal Floating-Point', packaged as a tar file which includes a README
file besides the source code. Th
I was wondering if anyone had some advice on how to handle the testcase
g++.dg/warn/multiple-overflow-warn-3.C. The test case fails on my HP-UX
platforms because the underlying type for wchar_t on HP-UX is 'unsigned
int' and not 'int' like it is on Linux. This means that the expression
does not

I thought of changing all the wchar_t's to int's but I think that might
negate what the test is trying to check since there would be no implicit
conversions in the code any more and the test would probably never have
given multiple overflow warn
