data file that triggers the segfault
Fedora 7 test bugs should be filed against "devel", not against test1/2/3. This isn't obvious, I know. Moving this report so it isn't lost. This is a bulk message -- I apologize if this was actually meant to be targeted against a different release. If so, please fix or let me know. Thanks. There seems to be problem with gprintf(util.c) procedure - the segfault happens when program try to write double variable (x), in format "%g" which should cause no error. Jakub, could you please look at it. This is a glibc bug, reproduced with current CVS glibc built for i686, using
union { long long l; double d } u = { .l = 0x3f1a36e2eb1c432cLL };
int
main (void)
{
__builtin_printf ("%g\n", u.d);
return 0;
}
*** Bug 236536 has been marked as a duplicate of this bug. *** Should be fixed in glibc-2.5.90-21. I can confirm my case to be fixed with -21 (bug 236536). Fixed for my case too. |
Description of problem: I get a segfault with: plot 'bug.data' using 6:($210-$95) I'll attach my data file bug.data. This is very strange. Backtrace is: (gdb) run Starting program: /usr/bin/gnuplot bug-temp.plt Program received signal SIGSEGV, Segmentation fault. *__GI_wmemset (s=0xbf959990, c=48, n=4294964831) at wmemset.c:33 33 wp[0] = c; (gdb) bt #0 *__GI_wmemset (s=0xbf959990, c=48, n=4294964831) at wmemset.c:33 #1 0x00b8193b in ___printf_fp (fp=0x30, info=0x30, args=0x30) at printf_fp.c:1088 #2 0x00000030 in ?? () #3 0x00000030 in ?? () #4 0x00000030 in ?? () #5 0x00000030 in ?? () ....... until infinity. I tried with FC6 gnuplot, same thing. That's a bit strange and it may not be a gnuplot bug but an issue with my libs or something like that. I run fedora devel.
