Replying to [comment:36 dimpase]:
> more details - it looks like "-g" flag does not work here:
{{{
$ cat conftes1.c
#ifdef __cplusplus
extern "C" { void underscore_test(); }
#endif
main () { underscore_test(); }
$
$ cat conftes2.s
.text
.globl _underscore_test
_underscore_test:
$
$ gcc -g -o x conftes1.c conftes2.s
collect2: ld terminated with signal 10 [Bus error]
ld warning: can't find atom for stabs FUN at 00000000 in
/var/folders/wg/wghOV5z8H7Ox9E0VSGnzm++++TM/-Tmp-//cc5M42pV.o
$ gcc -o x conftes1.c conftes2.s
$ ./x
$
}}}
> could it be due to "empty" conftes2.s ?
Indeed:
{{{
$ cat c2.s
.text
.globl _underscore_test
_underscore_test:
mflr r0
$ gcc -g -o x conftes1.c c2.s
$ ./x
$ gcc -g -O2 -o x conftes1.c c2.s
$ ./x
$ gcc -o x conftes1.c c2.s
$ ./x
$
}}}
So, one (not me :-( )needs to explain this to the autoconf, I suppose
