Package: gcc-4.0
Version: 4.0.2-5
Severity: important
Hi,
The latest upload of icon (9.4.2-2.4) has failed to build on arm with the
current gcc-4.0 in sid (4.0.2-5). After some investigation I've found
that this is gcc-4.0 fault, and the build failures start with the version
4.0.1-7 (4.0.1-6 builds the same source fine). Also, 4.0.1-7 works fine if
I change the optimization level from -O2 to -O0.
Since the failure is happening when the tests are run, it is pretty tricky
to tell what's wrong by looking at it with gdb (and the fact that the .c
source files for icon are generated from some kind of the pseudocode in .r
files does not help too much either). AFAICT it segfaults when trying to
dereference a pointer which has been defined and has a valid value in the
function, but at some point gdb starts reporting it as <value optimized
away> and the code gets a NULL when trying to dereference it.
Please let me know if you need more details and I'll try to dig into it.
