[Bug ada/18302] New: ACATS test c94002f hangs on Solaris 10/x86

[gcc-bugzilla at gcc dot gnu dot org]

Running the Ada testsuite on Solaris 10/x86 hangs in the c94002f test:
pstack reveals the following stack trace:

Unfortunately, the test can only be killed with kill -9, which lets the
whole testsuite run abort.  For the moment, I'm including the test in
norun.lst, but that file isn't platform specific, so with a shared source
tree, the test is disabled everywhere.

Environment:
System: SunOS erebus 5.10 s10_69 i86pc i386 i86pc
Architecture: i86pc

	
host: i386-pc-solaris2.10

configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --enable-languages=c,ada

How-To-Repeat:
Run make check as above.

Rerunning the bootstrap on 20041105 with s10_70 (i.e. the first build
supporting AMD64, but still running in 32-bit mode for the moment), the
same problems also affects c94002g, c953002, and c954022.

c953002 also hangs on sparc-sun-solaris2.8.

On i686-pc-mingw32, these three tests hang:

Executable    Run time   Memory Usage
c94002f.exe   0s         1112KB
c974012.exe   0s         1080KB

Andrew Pinski says:
I have the same problem with c94002f and c974012 on ppc-darwin

Does it still hang? Eric just commited a fix for PR18820 that is likely to have
fixed this problem.

(In reply to comment #17)
> OK, but sweeping the problem under the rug is not the solution on mainline.

I'm not advocating making these failures disappear; I'd just prefer they FAIL
rather than hanging, which disinclines one from running Ada tests at all.

> Probably no reason.

If there's no reason, then perhaps we can commit James' patch?  Allowing any
random Ada bug, particularly these which are probably not likely to be fixed
soon, to hang the testsuite on MinGW, doesn't seem sensible.

They work fine on other platforms than MinGW32.

A bunch of tests hang for me, some with 0% cpu, some with 100% cpu, on
i386-pc-mingw32 of 4.3.0.

Among the 0% CPU hangers is c960004

Among the 100% CPU hangers is c974013

Is there some reason that the proposed timeout fix that was applied to the RH
branch can't be applied to trunk?
