Bug 5402 – Invalid free() when throwing non-Throwable

class Foo { } void main() { throw new Foo; } When I run this code on 64-bit Linux, it produces the following error message: test.Foo *** glibc detected *** ./test: free(): invalid pointer: 0xf7458014 *** ======= Backtrace: ========= /lib32/libc.so.6(+0x6c231)[0xf75c2231] /lib32/libc.so.6(+0x6dab8)[0xf75c3ab8] /lib32/libc.so.6(cfree+0x6d)[0xf75c6b9d] ./test(_D4core7runtime19defaultTraceHandlerFPvZC6object9Throwable9TraceInfo16DefaultTraceInfo6__dtorMFZv+0xe)[0x80636aa] ./test(rt_finalize+0x5b)[0x8062b3b] ./test(_D2gc3gcx3Gcx11fullcollectMFPvZk+0x4a4)[0x8061e18] ./test(_D2gc3gcx3Gcx16fullcollectshellMFZk+0x26)[0x8061966] ./test(_D2gc3gcx2GC18fullCollectNoStackMFZv+0x29)[0x8060b61] ./test(gc_term+0x10)[0x805f320] ./test(_D2rt6dmain24mainUiPPaZi6runAllMFZv+0x59)[0x805d1bd] ./test(_D2rt6dmain24mainUiPPaZi7tryExecMFMDFZvZv+0x24)[0x805d0ac] ./test(main+0x94)[0x805d054] /lib32/libc.so.6(__libc_start_main+0xe6)[0xf756cbd6] ./test[0x805a991] ======= Memory map: ======== 08048000-0806e000 r-xp 00000000 00:15 4199206 /home/lars/tmp/test 0806e000-0806f000 r-xp 00025000 00:15 4199206 /home/lars/tmp/test 0806f000-08072000 rwxp 00026000 00:15 4199206 /home/lars/tmp/test 095b9000-095da000 rwxp 00000000 00:00 0 [heap] f7300000-f7321000 rwxp 00000000 00:00 0 f7321000-f7400000 ---p 00000000 00:00 0 f7436000-f7453000 r-xp 00000000 08:01 1059286 /usr/lib32/libgcc_s.so.1 f7453000-f7454000 r-xp 0001c000 08:01 1059286 /usr/lib32/libgcc_s.so.1 f7454000-f7455000 rwxp 0001d000 08:01 1059286 /usr/lib32/libgcc_s.so.1 f7455000-f7556000 rwxp 00000000 00:00 0 f7556000-f76a9000 r-xp 00000000 08:01 5898307 /lib32/libc-2.11.1.so f76a9000-f76aa000 ---p 00153000 08:01 5898307 /lib32/libc-2.11.1.so f76aa000-f76ac000 r-xp 00153000 08:01 5898307 /lib32/libc-2.11.1.so f76ac000-f76ad000 rwxp 00155000 08:01 5898307 /lib32/libc-2.11.1.so f76ad000-f76b1000 rwxp 00000000 00:00 0 f76b1000-f76d5000 r-xp 00000000 08:01 5898281 /lib32/libm-2.11.1.so f76d5000-f76d6000 r-xp 00023000 08:01 5898281 /lib32/libm-2.11.1.so f76d6000-f76d7000 rwxp 00024000 08:01 5898281 /lib32/libm-2.11.1.so f76d7000-f76ec000 r-xp 00000000 08:01 5898303 /lib32/libpthread-2.11.1.so f76ec000-f76ed000 r-xp 00014000 08:01 5898303 /lib32/libpthread-2.11.1.so f76ed000-f76ee000 rwxp 00015000 08:01 5898303 /lib32/libpthread-2.11.1.so f76ee000-f76f0000 rwxp 00000000 00:00 0 f770d000-f770f000 rwxp 00000000 00:00 0 f770f000-f7710000 r-xp 00000000 00:00 0 [vdso] f7710000-f772c000 r-xp 00000000 08:01 5898290 /lib32/ld-2.11.1.so f772c000-f772d000 r-xp 0001b000 08:01 5898290 /lib32/ld-2.11.1.so f772d000-f772e000 rwxp 0001c000 08:01 5898290 /lib32/ld-2.11.1.so ff922000-ff937000 rwxp 00000000 00:00 0 [stack]

Mass migration of bugs marked as x86-64 to just x86. The platform run on isn't what's relevant, it's if the app is a 32 or 64 bit app.

This is really a special case of bug 5447, rather than a straight duplicate; but anyway it is fixed in the next release. *** This issue has been marked as a duplicate of issue 5447 ***
