Dear all; I have envisaged a problem in my program and many a time I worked on it but I couldn't find the mistake. When I call the subroutine, the program runs until end of subroutine, but it cannot comes out of the subroutine. (the next command after calling the subroutine in the main program doesn't run.) you can see the error of run at below. Have you ever seen this error? I put the RETURN statement at the end of subroutine but it doesn't work yet. this subroutine takes (filname,j,k,m,y) quantities and makes a file that it's name is filname. (filname is acharacter and j,k,m,y are integer) After that I should use this file in main program. ----------------------------------------------------------------------- *** glibc detected *** ./wannier.exe: double free or corruption (out): 0x09165a88 *** ======= Backtrace: ========= /lib/libc.so.6[0xa4c424] /lib/libc.so.6(__libc_free+0x77)[0xa4c95f] ./wannier.exe[0x8061f33] ./wannier.exe[0x804e13d] ./wannier.exe[0x804f758] ./wannier.exe[0x8049f81] /lib/libc.so.6(__libc_start_main+0xc6)[0x9fdde6] ./wannier.exe[0x8049ec1] ======= Memory map: ======== 009c7000-009e1000 r-xp 00000000 16:02 2548379 /lib/ld-2.3.5.so 009e1000-009e2000 r-xp 00019000 16:02 2548379 /lib/ld-2.3.5.so 009e2000-009e3000 rwxp 0001a000 16:02 2548379 /lib/ld-2.3.5.so 009e9000-00b0d000 r-xp 00000000 16:02 2548380 /lib/libc-2.3.5.so 00b0d000-00b0f000 r-xp 00124000 16:02 2548380 /lib/libc-2.3.5.so 00b0f000-00b11000 rwxp 00126000 16:02 2548380 /lib/libc-2.3.5.so 00b11000-00b13000 rwxp 00b11000 00:00 0 00b15000-00b37000 r-xp 00000000 16:02 2548381 /lib/libm-2.3.5.so 00b37000-00b38000 r-xp 00021000 16:02 2548381 /lib/libm-2.3.5.so 00b38000-00b39000 rwxp 00022000 16:02 2548381 /lib/libm-2.3.5.so 00b3b000-00b3d000 r-xp 00000000 16:02 2548382 /lib/libdl-2.3.5.so 00b3d000-00b3e000 r-xp 00001000 16:02 2548382 /lib/libdl-2.3.5.so 00b3e000-00b3f000 rwxp 00002000 16:02 2548382 /lib/libdl-2.3.5.so 00d65000-00d6e000 r-xp 00000000 16:02 2548384 /lib/ libgcc_s-4.0.0-20050520.so.1 00d6e000-00d6f000 rwxp 00009000 16:02 2548384 /lib/ libgcc_s-4.0.0-20050520.so.1 08048000-080f0000 r-xp 00000000 16:05 2029792 /home/mirjani/Fortran/ Mmn-inside/wannier.exe 080f0000-080f6000 rwxp 000a7000 16:05 2029792 /home/mirjani/Fortran/ Mmn-inside/wannier.exe 080f6000-080fd000 rwxp 080f6000 00:00 0 09155000-09176000 rwxp 09155000 00:00 0 [heap] 40000000-40001000 r-xp 40000000 00:00 0 40001000-40002000 rwxp 40001000 00:00 0 40026000-40028000 rwxp 40026000 00:00 0 40100000-40121000 rwxp 40100000 00:00 0 40121000-40200000 --xp 40121000 00:00 0 bffe1000-bfff6000 rwxp bffe1000 00:00 0 [stack] forrtl: error (76): Abort trap signal Image PC Routine Line Source wannier.exe 080B7D23 Unknown Unknown Unknown wannier.exe 080B7343 Unknown Unknown Unknown wannier.exe 08072136 Unknown Unknown Unknown wannier.exe 08052180 Unknown Unknown Unknown wannier.exe 08053885 Unknown Unknown Unknown . 40000420 Unknown Unknown Unknown libc.so.6 00A12948 Unknown Unknown Unknown libc.so.6 00A4652A Unknown Unknown Unknown libc.so.6 00A4C424 Unknown Unknown Unknown libc.so.6 00A4C95F Unknown Unknown Unknown wannier.exe 08061F33 Unknown Unknown Unknown wannier.exe 0804E13D Unknown Unknown Unknown wannier.exe 0804F758 Unknown Unknown Unknown wannier.exe 08049F81 Unknown Unknown Unknown libc.so.6 009FDDE6 Unknown Unknown Unknown wannier.exe 08049EC1 Unknown Unknown Unknown ------------------------------------------------------------------------- Please let me know if there is anyone that has suggestion about this problem?
