Description Igor Bukanov 2006-05-07 08:06:44 UTC
Description of problem:

GCC crashes when compiling a C source from SpiderMonkey CVS HEAD, which is a JS
engine for Mozilla browsers.

Version-Release number of selected component (if applicable):
gcc (GCC) 4.1.0 20060304 (Red Hat 4.1.0-3)

How reproducible:

Run the attched preprocessed source against
/usr/libexec/gcc/i386-redhat-linux/4.1.0/cc1:

/usr/libexec/gcc/i386-redhat-linux/4.1.0/cc1 -quiet -ILinux_All_DBG.OBJ
-DGCC_OPT_BUG -DXP_UNIX -DSVR4 -DSYSV -D_BSD_SOURCE -DPOSIX_SOURCE
-DHAVE_LOCALTIME_R -DX86_LINUX -DDEBUG -DDEBUG_igor -DEDITLINE -DJS_VERSION=150
jscpucfg.i -quiet -dumpbase jscpucfg.c -mtune=generic -auxbase-strip jscpucfg.i
-g -Wall -Wno-format -o - -frandom-seed=0

Comment 2 Igor Bukanov 2006-05-07 08:37:19 UTC
Here is a minimal test case to trigger the bug:

int main()
{
    if (sizeof(long) == 8) {

        volatile static union {
            long i;
            char c[8];
        } u;

        u.i = 0;
        return (u.c[0] == 0x01 && u.c[1] == 0x02);
    }

    return 0;
}


Save it as test.c or test.i and try on FC5 for x86:

gcc -c -g test.c
gcc -c -g test.i
/usr/libexec/gcc/i386-redhat-linux/4.1.0/cc1 test.i  -g

In all cases the result is:
test.i:15: internal compiler error: in dwarf2out_finish, at dwarf2out.c:14116

If I remove -g, then there is no error (kind of obvious given the source bug)
